When I used to work in a prison health unit the docs advised the addicts (i.e. everyone) not to go cold turkey,  rather cut down to less than 10 per day, plus their methadone, and fucking managed alcohol withdrawals. We had to make sure anyone who had a baby had their health records kept for 10 years after their death or their 70th birthday, whichever was sooner. Some grim shit in those records.
