What's happening
You are still in the first week, which the NHS describes as the time when symptoms are usually strongest. For some people the urges ease a little after day 3. For others day 4 feels much the same. Both are normal.
Trouble sleeping is a common symptom. The CDC says it is common to have some trouble sleeping when you first quit, and that this gets better. Cleveland Clinic also lists insomnia and, less often, nightmares.
Caffeine is worth watching. The CDC notes that after quitting smoking, caffeine can affect you more than before, which can add to jumpiness and poor sleep.
What helps today
- Avoid caffeine in the afternoon and evening for now.
- Go to bed and get up at the same time each day.
- Put screens away before bed.
- If you use a nicotine patch and it disturbs your sleep, ask your pharmacist whether to take it off at night.
