This is a great topic. I am having the same problem. This is my second time using Chantix, The first time was last year and it worked beautifully for me, quit for about 6 months and made the terrible mistake one day of thinking I could have just one and here I am again. I am on my 7th day and don't really have any side effects except sleep problems. But I also don't seem to be having any less urges either. I set my quit date for Sunday 10/26 and today and until then I will be trying to be more aware of when I am smoking rather than just mindlessly lighting up. I do remember from last time that it did take a few more days until the urges were noticeably less so I guess I'll just see how it goes.
