I have tried to quit smoking
twice, once cold turkey (for 4 years), was VERY moody at first, and over the 4 years put on 20kg's. The second time, I took CHAMPIX, and honestly, they worked (while I was taking them), didn't have any withdrawals, didn't even think about them. I stopped for approx. 2 month's, they say the first 3 month's are the hardest.
