Welcome, puddin!
You are definitely in the right place. And I agree with Lil...long term treatment is the best part of your post. I was wondering, from your second post, was that his decision...to make it long term? If so, that's the best news you could want. That means he really wants to quit!
So many times my son would do a short stay in rehab, (for us, not for him) and then come out and use the same day. A month is just not long enough.
He's clean now and living in a sober home, where he plans on spending AT LEAST a full year. Many of the guys have been there 3 or more years, one even for 10 yrs.
There ARE alot of success stories here too, and long term rehab is really the best news you could have right now.
Now, how about you? You're scared and hurting and need to get help for yourself, too. Do you have any Nar-Anon groups in your area? Also, read through all the "sticky posts" at the top of the page. There's alot of help right there...for YOU!
In the meantime, keep posting! Sending out prayers for you and your son.
