Getting My Husband to Enroll in Class

My husband and I got married five years ago, and while things were great at first, I am not so sure that things are so happy now. We used to go out a lot when we were dating, and that was perfect because I would like to think of myself as a fun girl, but now it seems that he drinks even if we are not going out. I think that is a big problem, especially because alcoholism runs in his family. I am thinking of getting him to enroll in Drug Education Classes to prevent him from going on a downward spiral or something like that. The only thing is, I have to convince him that it would be beneficial for him to do that. I am not sure that he realizes it at this point, and I don't want him to get all defensive or anything like that.
