Hello. Any GTD smoking quitters out there? I'm quitting, and, well, I'm used to the constant stimulant. Of course, I'm still drinking coffee (and the constant imbibing of stimulants is bad for you and I exercise and that helps your energy more in the long run etc etc). Is coffee the only replacement stimulant for the cigarettes? It's really cutting into my productivity, and it will be very hard to maintain quitting if I'm at a permanently lower tier of work effort & focus.

thanks!
