Oh I hope that he is not and it is just the early 20's stuff that most people go through. I kinda preach to my daughter (early 20's too) and she tells me mom stop worrying, I will not have any problems with alcohol. I think we are super sensitive to it because of living with our A's and we do not want I precious kids to suffer the same way (or us for that matter). I wish there was a test for alcoholism. Why isn't there?
I would try and take a deep breath and not think to much about it at this point unless you start to see real signs of the disease rearing its ugly head. I think it is so much harder to deal with if it is one of our kids.
Big :ghug3 to you and a Happy Easter!
