Zyban is just wellbutrin or one of those antidepressants, so results may vary... i personally think it's a sham and a marketing ploy since it is not a very good antidepressant, but then i just ruined the psychosomatic results you might have gotten from it.... damn... seriously best way to quit anything is just to quit... tough it out for 48 hours and after 21 days bad habits are history alltogether.
