Icare, you'l find this interesting I think....

I'm a non-smoker. I have never even tried one puff of a cigarette in my life. When I was about 33 I had a very bad episode where I started craving cigarettes to the point that I was really fighting to not borrow them from co-workers. If I hadn't known I'd be embarrassed trying to smoke the first time in front of co-workers I probably would have done it, I was very, very badly craving it.

I didn't and got on a new AP and when the dose went up enough I stopped craving it. Nobody had an explanation for this although my pdoc was intrigued.

I think my body knew somehow what might help. It was so weird. I've been on hefty doses of APs since and it never has repeated.
