You say he was sober 9 months? Does that mean with a recovery program or just dry? Your question, though was about withdrawal. I doubt there is a lot of physcial withdrawal left after so long, most of it is mental. We try to self medicate to make ourselves feel better with alcohol and drugs. A whole can of worms opens up with a addictive personality. It is not easy to stay clean. If he really wants it, perhaps he will go to a therapist, that's a start.
do u know how much crack he smokes when he smokes?Crack does a helluva number on the brain and the central nervous system..user is crashed out after a binge....irritability and depression are common by themselves.....put alcohol on top of that and more depression.He sounds like my x who relapsed with his addiction after 3 years clean from it....would lie in bed sleeping long hours for days.....and the i'm going to stop!oh yeah!:)
