i had a very similar experience with a close family member.he had been into it all .all flavors of drugs for years.
he tried eveything.stopping starting.stopping starting,AA time after time.the amount of times he ratled while detoxing in unbelivable.this went on for 8 years.
he had full family suport the works.all the usual A+e,alcoholic fits, pnumonia.in the end HE booked himself into a detox/rehab center for a month.this was for alcoholics and real hardend junkies of which most where criminals. there as part of bail conditions.that was over 2 years ago.now he,s a completly different lad.
and quese what..
he,s a shit hot xc/dh dude now who loves life to bits.
i go riding with him often.
when i talk to him now it,s like he,s been reborn into one of the best lads you could ever meet.
so it,s a case of don,t give up on him because there,s someone else inside there dying to get out but doesn,t know how.
a nice positive story anyway.
