Usually when I quit smoking, I can't fall asleep that first evening without having smoked. But this goes beyond not being able to fall asleep. Basically, your body is tired and you're ready to fall asleep, but just as you do, these tingly pains start working through your muscles.

It hasn't happened to me recently, and I've been smoking and resting off and on for the past few months. But the times it did happen, it was always after I smoked. For a while, I thought I'd have to smoke the rest of my life to not go through that. Luckily, that isn't the case.
