I've been a smoker for about 8 years now, and at least two thirds of that time has been chronic use. I'm at a point where I am physically dependent. In the past when I would try to quit it was the mental aspect that bothered me the most. Now years later, whenever I am unable to obtain it I have no issues with the mental part, in fact I enjoy it. I find something else to do and actually get more creative than I normally might. Physically however, I just fall right apart. Usually at the 24h mark, it all suddenly and violently comes crashing down. I will get intense vomiting spells that will last for days even if I am able to resupply in that time. Along with migraines. I've read a lot of other long time chronic users saying they weren't able to sleep, had no appetite, and some mild-medium nausea but nothing even seems close to what happens to me. I could deal with those things but my symptoms are totally debilitating and my life cannot afford the time to just be sick for a week or more. I would really like to quit now, but I'm unsure how to tackle this problem. Has anyone here had a similar experience?
