My mother has a drinking problem and she stopped drinking altogether with Esperal. She said that AA was a waste of time for her and actually made it worse. This might not be so for your fiance but that's how my mum stopped drinking. I hope everything goes well for you. I know how destructive alcohol addiction and dependance can be and I spent most of my childhood with my mum being on and off the wagon. Esperal is how she stopped but you might want to look into it first. I wish you all the best!
