Hello, this is my 3rd day of taking zyban ( quit day next wed). I'm jot sure wha time of day to take it. I'm up at 5 am for work.l, doc said take at about 10 but I reckon maybe the earlier the better as the rejecting fag taste will start earlier. Any ideas anyone? Anybody used zyban? I have tried champix twice and managed 4 months, am going for diff buzz this time. Hope it works.
