Oh, one more thought:
Yoda says, do not try, do. There is no try.

I quit smoking for about three years, started again last year because of work stress, and frankly, it's a stimulant and I need it to keep up the insane work schedule I have lately. I'd tried many times before that, but it didn't work out very well. The thing that really helped was realizing how nicotine works on the brain.

From what I understand, nicotine alters the brain chemistry such that it causes the cells to actually need nicotine to function properly. Their base comfort state is with nicotine present. It occurred to me that these little cells are probably sending out distress signals, which, in the brain, causes thoughts. Therefore, none of the bull**** reasons, rational or irrational, to smoke are actually real. Your brain will come up with all sorts of wild reasons why you should smoke. Ignore it. It's wrong.
