Hi Nicodemon:
Today is also my first NON smoking day on Zyban. I started taking Zyban a week ago, today is the 8th day. Not easy, seems like the cravings aren't as bad as long as I'm busy. When I have a lull in my day, that's when I start to go a little crazy. Hope you had a GREAT smoke free day and look forward to reading your posts to see how you're doing. My husband is taking Chantix and is also feeling the same way. Lots of luck, health and wonderful wishes to you!
