Definitely talk to your doctor about the issues you are experiencing. I had two friends that experienced very bad side effects but I never did. It did reduce my cravings but I soon realized when I did drink I didn't have the drive to drink as much. So my mind twisted it into I could take it and drink socially and like other people. Eventually I'd quit using it and be too messed up to make the appointment to get more and use it correctly -.- I wasn't committed to sobriety then really looking for something to make me able to drink normal. Used with abstinence I've heard it be successful.
