Zyban
"I'm taking contrave which contains zyban. Immediately my cravings were dramatically reduced. I was completely shocked because I've been trying to quit for 30 years without success. I'd always get the most unbearable tension headaches and give up. Finally I asked my doctor for help and she prescribed this. It's been almost a month now and I've only smoked a few times. It tastes horrible now and I'm not craving them at all now unless I get really stressed out. But when I do, I don't enjoy it anymore. I encourage you to try it. If you get side effects reduce the dosage til your body adjusts. Increase very gradually. Hope this helps! Good luck!"
