MYJoey,
I agree with Ann 100%. I too have had to learn the hard way that there was nothing I could do to make my son want to be sober or keep him that way. He had to want it bad enough for himself. I hope your son truly wants to be sober and having 8 months behind him last time is great. Hopefully he can do it and is willing to do whatever he has to to maintain it. The best thing you can do is support him emotionally and tell him you are there for him as long as he stays sober. Giving him strict boundaries is an excellent way of letting him know what you expect from him if he plans on staying under your roof. You put him out once so he knows you will do it again should he not follow your rules. I wish you the best and will keep your family in my prayers. Dealing with a family member with a drug problem is one of the worst things I have ever been through. I wouldn't wish it on my worst enemy. Hugs.
