I have manage to go the whole day.. really 24 hours without a cigarette . Very good for me since I've been a 31 year smoker and up to 2 packs a day..... That's a long time and a lot of cigs.. I'm not that trilled to stop smoking but gotta do what I gotta do. I've only tired one other time to stop, that lasted 2 months and a gain of 20 lbs. I'm trying Chantix this time. An awful pill really, if I don't take it after I eat, I'm nausea. I take it twice a day, first thing in the morning when I have the hardest time trying to eat something.. anyway, I want one now bad, probable because I'm writing about it. guess I should stop and just go to bed...
