I am using Chantix and today is 51 days that I haven't smoked. I have had the most ridiculous stressful situations (including PMS and getting a restraining order!) and haven't had the need to pick up a cigarette to solve anything. I did read all the news reports about some of the new side effects of Chantix and I swear I had the heart palpitations that I read about. But I bet that was my formerly smoking self trying to derail me. Now that we're going into the Memorial Day holiday with all the social events and barbeques, I am re-committing myself. NO THANKS, I DON'T SMOKE. Have a wonderful long weekend everyone!
