Acamprosate
"I have been on Campral for only five days now. Previous drinking was about 3 cases of beer a week and two of those being on the weekend.  Past weekend - as everyone else here has reported - no cravings for beer.  Usually, if I was trying to not drink on the weekends, the craving would be persistent about every two minutes. It just didn't have the appeal.  Really weird but it seems to be working.  Also, not centering the day around being able to drive, and I know a DUI was getting very close. That is what scared me into doing something and I am glad for doing so.  The cost savings of an estimated 300  dollars per month is already felt. So went shopping since I could drive and had extra money. Small reward."
