Congratulations on quitting – that’s a HUGE accomplishment! The next step, of course, is to get through the aftermath of quitting without going back to smoking, right?
Insomnia is a common problem after quitting, but rest assured it’s temporary – once your body adjusts to not smoking, you will sleep better than before, and wake up much more rested than you did when you were smoking.
What’s happening is this: Nicotine affects your sleep patterns, and after you quit, it takes your body a few weeks to readjust to the new patterns. Research shows that smokers spend more time in alpha (light) sleep, and less time in delta (deep) sleep. When you quit, some of the time you were spending in light sleep ends up breaking the surface into wakefulness, meaning that you wake up multiple times during the night.
The good news is, as long as you stay off of nicotine, within a few weeks your body will gradually adjust on its own so that you revert to the sleep of a non-smoker: more time in deep, restorative sleep, less time in light sleep, and no waking up multiple times in the middle of the night.
The normal techniques for dealing with insomnia should help you get some sleep during this adjustment period, as well as help to get your body on track for normal restorative sleep patterns:
