My quit date was testerday the 25th but I quit 4 days ago and I am doing fine the chantix is wonderful never thought it would work as good as it has.I have had no side effects at all but I do make sure I eat a good meal before every pill.I still want to smoke but it smells awful to me so I just stay away from it.I will do this and then I will no that I will live a long healthy life.....
