I also used Zyban to quit. Trust me, it works. Perhaps not as well for me as for him. That's the breaks. The bad, rotten, really TERRIBLE thing about zyban is that, here at least, it costs us$150 per month. I have very good insurance and it wasn't covered. If you know a cat, or maybe know a cat who knows a cat. TELL THEM. Every one here is in favour of quitting. Why keep one of the best tools out of most peoples reach?
