This is the only time I went to an actual clinic to detox but I signed myself out after 3 days. I started using but smaller amounts for the next few days then I quit cold turkey from home.  During the next 3 months I relapsed only on 2 occasions. Then I started using again a 3rd time and continued daily after that basically until present day. I attempted to quit on 2 different occasions. Both times I took time off of work in preparation of getting thru withdrawals. However, the 1st occasion lasted hours before using heroin again and the 2nd time, I went 3 or 4 days, then started using again. I have done methadone clinic programs at least 3 times over the past decade. I've been fairly successful at abstaining from illicit drug use doing this program until my crystal meth addiction became what it is and graduated from social use to regular use and now functioning without it is near impossible. I'm not currently in methadone program but was looking to get enrolled again in the very near future. I'd prefer being clean than being dependant on anything ...even if is legal to be on a methadone maintenance program.
