I used to smoke at least 2 packets per day for almost 20 years. I severally tried to quit without sucess. 😀 It was in 2018 while visiting a doctor friend when I learnt about the wonder drug zyban and decided to give it a try. I've got it from "GETZYB2SS" (you can search on Google, I don’t remember the link). I’ve got great results with it. I took 1 tablet per day for 1 week and has never looked back. 😀 No claving and no side effects. After 1 week of no smoking at all, I gave the rest of the medication to a friend. The way I think zyban has a degree of success is when an individual also desires and is determined to quit. All I needed was 3 days of no smoking
