Quitting smoking.
Congratulations! Keep it up!
I quit August 2001. I was extremely glad I did. I volunteered to be part of the first group from my base to deploy on Sep 11 2001. When we arrived to a bare base in the dessert, you can imagine, all the smokers were hard up for cigarettes and there were none to be found. A couple months later when most of us left there but a few had to stay behind, I sent them 8 cartons of cigs a week later from the other country that we went to.
Good luck to you. It will get easier.
