Hi Deb, I worried that I wasn't going to be a success with Chantix because I had taken it once before and never did quit....this time I just plain wanted to quit....I took Chanitix for 7 days and quit on the 8th...I read that it does take longer sometimes to get in the system, anyway that was on June 2 and I'm still smokefree...I also had the vivid dreams but I like them, I'll dream then wake up and when I go to sleep again it continues...mine have not been horrible just funny ones...I quit taking the evening pill after about a month and a half and I have been fine ever since with one, my Dr. told me to keep taking them until they are gone so I just started the last month which will last me 2, Chantix is good but it doesn't do everything you still have to be strong and use every ounce of will power you have sometimes...good luck Deb, I hope you have as much success as I have had...
