Also not bashing rehabs, but they seem to be a hothouse for people hooking up. It amazes me every time I hear it, and I am pretty sure looking back that my XAH was in that camp when he went too. Just amazing.
I always say that the best thing you can do for any program you plan to attend is to research it and if it's not the right one, try out another. If you don't like AA, try Celebrate Recovery or another type of group. Or another home group.
As far as rehab, I really believe that when they go if you don't do some research and pick the first available bed, it just turns into a hot mess unless you just get lucky.
Just my .02. Definitely not bashing either b/c I know both help tons of people. It's just important to get help from the right place. Thank God for SR!
