I think it requires medical supervision. I took it in a hospital, very low dose, with morphine after a bad car accident. Before I could be released they weaned me off of both. I felt very strange on the drugs and was glad to get off...I however don't know which drug caused the feelings or if both did.
We do not know how to help withdrawal...I wouldn't do it. I'd be afraid.
God bless you and your son.
