Though out the years when ever I quit smoking be it from being Ripped once with shotguns, (kinda scared me straight) or to just needed or wanting a break.The worse thing I found was the dreams that showed up that weren't there when I was smoking. But after a little while I learned I really enjoyed the dreaming so I haven't smoked but once or twice in the last 12 years..Good LuckThe first week was hard mentally but I never really got physical symptoms of withdrawal. I have been having problems sleeping though (waking up from nightmares several times during the night...) whereas when I was smoking I rarely woke up/remembered my dreams. Weird.
