So I am on week 3 of Chantix. I absolutely think it's wonderful. I quit smoking on June 18th. I am so thrilled about it! Even in all of the craziness that is going on in my life.. (long story) I managed to quit.. and that's living with 2 people that smoke.. 1 of which who smokes 2 1/2 cartons a week.. that's right.. you didn't misread that. So, I'm doing pretty good. I just wanted to share!
