There's no seven-day version of this, and anyone offering one is working from a model of the reward system that doesn't hold up.
What follows is what the literature suggests when enjoyment has flattened: ordered by impact, honest about timescale, and clear about where the boundary is. If you want the why first, when nothing feels enjoyable anymore covers the mechanism. This page is the what-to-do.
Start with the shape of the problem
If enjoyment has faded, the useful framing isn't an empty tank. It's a setpoint that moved.
Reward function is normally held inside a range by opposing processes. Under sustained load, those processes can stop restoring it, and the system settles lower: a shifted setpoint rather than a drained level. Everything then gets measured against the new reference, which is why good things stop registering as good.
That framing sets three expectations. Movement is possible. It's slow, roughly in proportion to how long the load ran. And it shows up as drift rather than a switch flipping, which matters for how you judge progress at week three.
It also tells you what kind of plan works. Not a purge. A set of small, repeated changes to the inputs, held for long enough that the reference point has time to move.
Sleep, first and unglamorously
It's the item with the biggest payoff and the least interest, which is why it gets skipped. The clearest human data point is Volkow et al. (2012). In 20 healthy adults scanned with PET, one night without sleep lowered the availability of D2/D3 dopamine receptors in the ventral striatum, a core part of the reward circuit, and the size of the drop tracked how sleepy people felt. The authors read it as the receptors being turned down rather than extra dopamine being released.
The limits are real: 20 people, one night of total deprivation, and an indirect inference from imaging. It does not show what weeks of six-hour nights do. But it points in a consistent direction, and it's the cheapest variable on this page to test.
If sleep has been poor for weeks, it caps everything else. Behavioural changes layered on top of a sleep deficit tend to underperform for reasons that have nothing to do with the behaviour. If only one thing changes, make it this one.
Schedule the doing before the wanting
The most common trap when things are flat: waiting to feel like doing something before doing it. When enjoyment is low, that feeling arrives late or not at all, so nothing gets done, and the flatness confirms itself.
Clinicians who treat depression have a structured approach built around reversing that order. It's called behavioural activation. You schedule small activities in advance, chosen for what you value or used to enjoy, do them whether or not you feel like it, and record how they actually went. Motivation is treated as something that follows action, not something that has to precede it.
The evidence base is clinical, and it's reasonably strong. In Dimidjian et al. (2006), a placebo-controlled trial with 241 adults with major depression, behavioural activation matched antidepressant medication among the more severely depressed patients, and both did better than cognitive therapy in that group. That last comparison hasn't held up elsewhere, so read it as one site's result. A meta-analysis by Ekers et al. (2014) pooled 26 trials with 1,524 participants and found behavioural activation beat control conditions by a standardised mean difference of 0.74, with the caveat that most included studies were low quality with short follow-up.
Two things follow. First, this is a treatment for a clinical condition, and if you might be depressed, the right version of it is with a professional. Second, the core idea transfers to ordinary flatness: plan the activity, do it, then rate it. You'll often find the rating is higher than the forecast you made while flat, and that gap is the useful data.
Savor on purpose
Enjoyment isn't only about what happens. It's also about what you do with your attention while it happens.
Bryant & Veroff (2007) define savoring as attending to, appreciating and amplifying positive experience, whether it's happening now, remembered, or anticipated. It's a skill rather than a trait, and it can be practised.
Quoidbach, Berry et al. (2010) asked 282 adults how they respond to good events. Savoring strategies, such as staying present, telling someone, and looking back on it later, went with more positive emotion and higher life satisfaction. Dampening strategies, such as finding the flaw or telling yourself it won't last, went with less. That's a cross-sectional survey, so it shows association, not that savoring causes well-being.
A second study from the same group, Quoidbach, Dunn et al. (2010), found that students primed with images of money spent about 15 seconds less savoring a piece of chocolate and enjoyed it less. It's often quoted. Treat it with caution: money-priming effects in general have a poor replication record.
The practical part is the defensible part. When something good happens, stay with it for a few extra seconds instead of reaching for the next input. Tell someone. Look back on it that evening. Each of these is cheap, and each works against the reflex of moving on before the experience lands.
Rotate, so it doesn't fade again
Even when enjoyment comes back, it can quietly wear off again. That's hedonic adaptation: responses to repeated or constant experiences weaken over time, as Frederick & Loewenstein (1999) reviewed in a chapter that also covers the limits of how far people adapt.
What slows it? In a longitudinal study, Sheldon & Lyubomirsky (2012) followed students after a positive change in their lives. The gains lasted longest when the change kept producing variety and fresh positive experiences, and when people kept appreciating it instead of raising their expectations. Student sample, self-report, but the finding fits everything above.
In practice: vary the pleasant things rather than repeating one. A different walking route, a new recipe from a familiar cuisine, a different friend for the weekly call. Variety resets the adaptation clock; the same reward on repeat wears it down.
Change structure, not volume
The instinct is to cut totals. The literature points at shape instead. Make one unpredictable reward predictable. Variable-ratio schedules train checking hardest, and converting a single frequent one into something scheduled does more than deleting several predictable ones: the schedule is the variable, not the hours.
Put effort in front of something. Effortful rewards behave differently from frictionless ones, and small friction buys most of the benefit. The point isn't difficulty. It's that something preceded the payoff.
Reduce frequency before duration. Forty small hits a day tend to cost more than one planned session.
Keep the things detox tells you to cut
This is where most attempts go wrong. Exercise, cooking, music, people, being outside, work that is hard and yours: these are effortful rewards, and in a load model they're protective, not indulgent. A protocol that removes them alongside the feeds strips out the half that was helping. Detox reasoning doesn't hold up for exactly this reason. If your baseline is already low, austerity adds load.
A first week
Seven days won't fix this, but they will set it up. Each step ties to one of the sections above.
- Fix the sleep window. Pick a wake time and keep it all week, weekends included. Put the phone outside the bedroom. Everything else depends on this.
- Schedule three small activities in advance. One physical, one social, one you used to enjoy. Put them in the calendar with a time. Before each, write a 0 to 10 guess of how enjoyable it will be; after, write the real score.
- Savor one thing a day. When something is good, stay with it for an extra half minute. At night, write one line about it.
- Make one feed predictable. Choose the app you open most and give it two fixed times a day. Leave the others alone for now.
- Add one new variation. A new route, a new recipe, a new piece of music. Novelty is cheap to buy and works against adaptation.
At the end of the week, compare your forecasts with your actual scores. If the actuals beat the forecasts, that's the flat reference talking, not the activities.
Expect drift, and measure direction
The failure mode isn't giving up on day two. It's reaching week three, feeling noticeably better rather than restored, and reading that as failure.
A modest, sustained improvement over a few weeks is the shape of a setpoint moving. It doesn't feel like a result because you can't perceive a reference point shifting from inside it. You only notice the level. That's the argument for writing something down rather than relying on how the week felt.
The boundary, stated plainly
Some flatness isn't a loaded reward system. Persistent loss of enjoyment is a recognised clinical symptom, called anhedonia, and a core feature of depression. It also appears in other conditions and as a side effect of some medications. It can't be distinguished from the inside, and no tracker or article can distinguish it either.
If the flatness has lasted more than a couple of weeks, covers everything rather than specific things, or comes with hopelessness, changes in sleep or appetite, or thoughts of hurting yourself, talk to a doctor or a mental health professional. That is the highest-value action available, well above anything on this page. If you're in immediate distress, contact your local emergency services or a crisis line where you are.
How Myo uses this
Myo models your reward balance from what you log in plain sentences: sleep, effortful activities, feeds, and the rest. It does not measure dopamine, and it can't tell flatness from depression. What it can show is direction over weeks: whether modelled load is accumulating or clearing, how much of your day arrives without effort, and which single change would move the balance most. The weights behind that are Myo's modelling choices, published mechanism by mechanism on the science page. If you want a starting point, the 60-second audit names one lever. There is also no at-home dopamine test, and here is what a self-check can and can't tell you. More on flatness lives in the feeling flat guide.
FAQ
How long does it take to start enjoying things again?
There is no fixed timeline. If the flatness comes from load such as poor sleep and frequent unpredictable reward, expect gradual change over weeks rather than days, roughly in proportion to how long the load ran. The first signs are usually small, such as one activity scoring better than you expected. If nothing shifts after a few weeks, or it is getting worse, speak to a doctor.
Can I do behavioural activation on my own?
The core idea, scheduling small valued activities and doing them before motivation arrives, is simple enough to try on your own for ordinary flatness. The trials that support it, though, were run with depressed patients and trained clinicians. If you think you might be depressed, the structured version with a therapist is the one with evidence behind it, and it is worth asking a doctor for a referral.
Why don't I enjoy my hobbies anymore?
Often it is a combination of fatigue, a shifted reference point and adaptation. Poor sleep blunts reward, a day full of effortless input makes effortful hobbies feel expensive, and doing the same thing the same way wears off over time. Fixing sleep, scheduling the hobby rather than waiting to feel like it, and changing one detail of how you do it are reasonable first steps.
Does savoring actually make you happier?
Survey studies link savoring habits, such as staying present, sharing good news and remembering good moments, with more positive emotion and higher life satisfaction. Those studies show association rather than proof of cause, but savoring costs nothing and carries little risk. The practical version is to stay with a good moment a little longer than usual and to revisit it later the same day.
Is there a way to reset dopamine naturally?
No method has been shown to reset dopamine, natural or otherwise, and nothing you can buy measures it. What the research does support is changing the inputs: protecting sleep, adding effortful and varied activities, scheduling them in advance, and making frequent unpredictable rewards more predictable. Those changes can shift how enjoyable things feel over weeks, without any claim about resetting a chemical.
