Hi Aim - I am new to this forum too. Glad to hear you are having such success with Zyban. I used a different method to quit, but have been smoke free for almost a year now. I smoked for 35 years, 1.5 packs a day or more. I'm curious are you having any side effects, using the zyban? Also, how is it doing in diminishing the cravings? I still have a craving every now and again, but it goes away pretty quick.
