Varenicline
"Started smoking when I was 18 and have smoked a pack a day for 17 years. NEVER thought I would be able to stop. Well I have with Chantix. I quit on my quit day and haven't looked back. Started running to fill the down time. I am on the second week which is 2 blue pills a day but only did that for 2 days. Currently on 1 pill as I did have trouble falling asleep. That has been my only side effect. No nausea and no nightmares - but I do have VERY vivid dreams which I actually enjoy. This is a miracle drug for me. I wish it could work for everyone like it is working for me."
