Has anyone tried Champix more than once before it actually worked? My first quit with Champix lasted a yr, my second attempt with Champix lasted a month but the hubby thought it wasn't agreeing with me so wanted me to come off them so of course I was straight back smoking again. I personally thought I was ok. Thinking of giving it another try but I do have my 'moments' so afraid it's going to mess with me head! Advice/ experiences anyone???
