Varenicline

Have you had the chance to start patients on Chantix yet?
What has your experience with it been thus far? Any good success stories?

Smoking cessation

JJ had posted on the JAMA article on Varenicline (Pfizer's Chantix for smoking cessation).
Has anybody had a chance to prescribe it yet?
There is a reported fairly high rate of nausea but it is also reported to be mild and transient. Any experience with that?

Smoking cessation and Varenicline

This week's JAMA (296:47-55) by Gonzales et al. has a study on smoking cessation with the new Acetylcholine receptor agonist Varenicline. It was a phase 3 randomized DB comparing 52 week abstinence between Varenicline, bupropion or placebo. Fairly compelling results with few side effects in a minority (nausea and insomnia). I wonder how expensive this stuff will be...
