Marrisa, there's a Friends and family of substance abusers forum here. You might want to also ask in that forum too. I've never had a loved one go through rehab but I have. It's really going to be up to the individual on whether its successful or not. So no one is going to be able to tell you with any certainty. I was sober for 9 months but part way through my wife at that time said she wanted a divorce, the marriage was rocky for a number of years. I ended up relapsing. 10 years later I'm back here. This time doing it for myself and not to save a marriage.
