Like mentioned above he either needs to start seeing a suboxone doctor in order to get be tapered properly or he needs to enter a detox facility. Either way he needs to start working on recovery by going to NA meetings and an addiction therapist. Just about the only way for sub to be a successful alternative to getting off of other opiates is to work a recovery program. Suboxone isn't some magic pill to get you off of opiates. It's a whole program.
What's a good detox to withdrawl?
Detox...esp since he was NOT the one prescribed the medication.
Sub needs to be taken under a doctors supervision along with therapy. How long has he been taking this?
