I work in a drug and alcohol detox/rehab. We use methadone and suboxone to treat opiate withdrawal, except they cant have suboxone if they have been on benzos or using alcohol. We use phenobarbital to taper people off of benzos, and we use Librium for alcohol withdrawal. Where I work it's a mix between medical and psych, but leans more to psych...all the patients have to pretty much be medically stable to be there...we dont have IVs or stuff like that. Also, know what withdrawal symptoms to watch for, for benzos and alcohol clients, the big thing to watch out for are seizures. Also, these clients can be very manipulative, so remember to be firm, fair, and consistent. It's a great field to work in. I've been doing it now for about 2 1/2 years. Best of luck to you!
