Chantix
"I've been taking Chantix for nine days, after having been a  2.5 - 3 pack-a-day smoker for 44 years.  Because of the length and strength of my addiction, I supplemented Chantix with smoking cessation hypnotherapy.  I have had no side effects.  I'm terrified of gaining weight, so the hypnotherapist includes suggestions such as "I will not snack" during my sessions.  He also includes "no irritability" suggestions. I've  taken to drinking diluted grapefruit juice instead of diet soda.  I'm down to seven cigarettes a day.  I still have triggers - like sitting at the computer - but, overall, cutting down on the way to quitting has been easier than I anticipated."
