I do not recommend it! I know that your instinct is to help him, but you have no idea what you're in for. I tried to help my son's father with this and it was horrifying!!! It is an extremely physical withdrawal. Meaning, lots of vomiting, convulsions, seizures, etc. Basically, unless you are mentally and physically strong enough, it's nearly impossible. I don't know where you live, but in the states you can go to your local social services office and get him on medicaid or some of the detox places will help him get on medicaid. I hope this helps!Has anyone had an adult child detox from fentanyl at home. My adult son is wanting to come home and detox. He has been shooting fentanyl for a while now.
