Hey nice, I am not you but I wouldn't tempt myself with a drug while quitting. I smoked at that sabotaged my efforts a few times before I quit. I'm not exactly down with the AA type always an addict thinking, but it is worth remembering that brains take to things differently and vulnerability can remain. I don't take nicotine or coke anymore because while I'm pretty sure I would be able to use it and stop I know it would be unpleasantly hard to do so.
I drink to much atm, it got out of hand during a bad period of chronic pain and it's been a struggle at times. Posts like this are encouraging.
