Pyro, you are way ahead of the game it seems, but the game has a means of catching up to you fast. Remain vigilant. I cannot speak for everyone's quit, but I can share a quick experience about alcohol as it relates to my quit. The first couple of weeks in, I did decide (unknowingly) that I was going to switch the nic bitch for alcohol. If I was off work, I was drinking. Anything to make me forget how I was feeling. It took me bringing my wife to tears to realize what a drunk ass clown I was. I had not drank like that since I was in college. Luckily, I realized what I was doing, and started exercising. Now, I still like my cold beer, but I definitely don't let it get the best of me.
Moral of that story is, nicotine has a way of getting at you one way or another. Once you quit her, it can be a slippery slope. Every day is a challenge to be better than yesterday. I have no doubt that you can do it. Stay strong, stay responsible. Quitting with you today.
