My xah did intensive outpatient program and also an inpatient program. The out patient one was 30 days after detox. The inpatient was a 4-6 week program but he stayed longer to deal with anxiety (I guess - my info is sketchy at this point as we were already divorced). He said the inpatient program was really great - way better. He has had more success with but he has a hard time coping away from their programs - probably because he doesn't do follow up meetings. Also, our marriage was falling apart when he did the inpatient so he had more stress etc. We were already divorced when he did the inpatient. He is no longer in a rehab but still affiliated with them and so continues to get follow up there etc. He went through the VA. I hope he can carry those tools with him and remain in recovery once he moves away from their systems etc.
