Withdrawal isn't one feeling — it's several different ones, each with its own shape and its own way of easing off. Knowing which symptom you're dealing with in the moment makes it much easier to respond to, instead of it just feeling like generalized misery.
Cravings
What it feels like: a sudden, specific pull toward using — often triggered by a place, time of day, or feeling rather than appearing at random.
How long it lasts: individual cravings almost always pass within five to ten minutes whether or not you act on them. The frequency of cravings (not their intensity) is what gradually drops over the following weeks.
What helps: treat each one as a wave with a peak, not a constant state — set an actual timer for five minutes and do something else until it goes off. See our guide on riding out a craving for the specific technique.
Irritability and mood swings
What it feels like: a shorter fuse than normal, snapping at things that wouldn't usually bother you.
How long it lasts: typically most noticeable in the first week, easing substantially by week two.
What helps: naming it out loud, even just to yourself ("this is withdrawal, not actually about this") tends to defuse it faster than trying to push through silently. Giving people around you a heads-up that you're quitting can also take pressure off both sides.
Trouble concentrating
What it feels like: difficulty focusing on tasks that are normally easy, a kind of mental fog.
How long it lasts: usually most pronounced in the first week, improving steadily after.
What helps: lowering your own expectations for output during the first week specifically, rather than fighting the fog. Short breaks and short bursts of activity tend to work better than trying to force a long focused session.
Restlessness
What it feels like: physical fidgetiness, difficulty sitting still or relaxing.
How long it lasts: most intense in the first several days.
What helps: physical movement — even a short walk measurably reduces this — and having something to occupy your hands specifically (see our list of things to do instead of a pouch).
Sleep disruption
What it feels like: trouble falling asleep, waking up more during the night, or unusually vivid dreams.
How long it lasts: commonly worst in the first one to two weeks.
What helps: keeping a consistent sleep schedule even when sleep itself is rough, and avoiding caffeine later in the day than you normally would — withdrawal already makes sleep harder to come by without extra help working against it.
Increased appetite
What it feels like: genuinely feeling hungrier, or reaching for food in moments that used to call for a pouch.
How long it lasts: often continues for several weeks before settling back toward your normal baseline.
What helps: having a planned, low-effort substitute on hand (gum, a particular snack, cold water) so the habitual "reach for something" moment has somewhere to go that isn't unplanned.
When to actually be concerned
Everything above is a normal, expected part of quitting nicotine. If symptoms are severe, you're experiencing thoughts of self-harm, or you have underlying health conditions that make nicotine withdrawal riskier to manage on your own, talk to a doctor — this is general information, not medical advice for your specific situation.
For the bigger-picture shape of how all of this unfolds over time, see our week-by-week withdrawal timeline. And if it helps to actually see your cravings-resisted count climb instead of just weathering them invisibly, that's what Norvayo's tracking is for.
