Winnie - I'm sorry you're not even getting peace with your AS in rehab! I'd wonder about some kind of chemical imbalance as well. Could you talk with the rehab about this? I know you can't compare addicts, but have you asked them how your AS compares to the other patients as far as mentality/thinking/ and if they think further testing would be helpful? I'm glad he's in there for a long time, that's what he needs.
