"I've been a 1/2 pack a day smoker for 10years, I'm now 27 and decided I was done with smoking! I'm on day 4 of Chantix and today I've felt no urge to NEED to smoke it really was out of habit this morning, so strange not having that feeling of the release when I would finally get a cigarette. I'm sure I could have went without that 5:30am cig, it's 6hours later and I don't have the NEED to have one. I am expericing nausea for a few hours after the AM dose but nothing that isn't tolerable. Also I have Aetna and it was completely covered, $0 out of pocket."
