I don't know if it will hinder progress on this WOL, but my Mom did take it to quit smoking. The one thing that really affected her was that it totally killed her appetite. She was already thin and dropped 14 pounds. She gained it back when she went off it, but it was a very dangerous and pronounced side-effect. So, I thought it might help you to be ready for that side-effect and be aware that you may have to force your food down or you will end up stalling and burning muscle. Good luck!
