I once had a very bad episode and CRAVED cigarettes. Which is kind of weird since I have never smoked even a puff of one. I don't even know HOW to smoke. But my body wanted nicotine desperately, so much that I was fighting to not beg others to "borrow" cigarettes and I am still pretty amazed I made it through that without starting to smoke. But it truly was like my body knew that the chemicals would provide relief and it was out to get it any way possible. My psychiatrist and therapist had never heard of anyone having this but it was very real and very difficult. Instead I got Seroquel which was the first AP that actually worked for me without sending me to the ER. I still wonder sometimes if the Seroquel (and now the 2nd AP) were taken away if I would be a smoker. Probably not because I couldn't afford it and I'm very strict about budgets. But I'd hate to think I'd still be wanting to smoke because that was a heavy, heavy craving.
