Thanks for your post Kimberly. I have only been taking the Zyban for about 6 or 7 days and am still weaning myself off the Dex so I won’t know for sure until I am completely off the Dex. I hope it works. I’m glad you found that Concerta was the right one for you. I am hoping this one is the right one as I don’t want to have to try another one.
