I hope to get some advice from other parents who faced a similar problem. I know that college is the time to experiment and try new things, but I've never expected something like this would happen to my son.

Initially, we used to facetime every day when he went to college. In about a couple of months, he said he had found new friends and was busy studying. Since then, he only texted us a couple of times a week. Everything seemed fine, we thought he was immersed in studying as he claimed, and we didn't think there were any problems. The only thing we've noticed during the Christmas break was that he lost a lot of weight.

When he came home on spring break, we realized, to our horror, that he became addicted to alcohol to the point of sneaking out to have a drink even when he's back home. And I'm not talking about a couple of beers with his friends because I would be ok with that. He drinks some heavy stuff like vodka or whiskey and reeks when he comes back. I just don't recognize him anymore.

We don't have alcohol in our house and never had anyone addicted to it in our family. We had a talk about the harmful effects of alcohol abuse a couple of times after seeing some dreadful stories on TV, and I thought that our conversations have had the due effect. Apparently, that wasn't enough to convince my son not to ruin his life.

My question is whether there are some effective rehabs we can get him into? If anyone had experience with being in one themselves or getting your loved ones into rehab, I would immensely appreciate the tips. 

I'm just at a loss and willing to hear any advice or tips on how to help him.
