methadone to abstinence is the most comfortable but its hard to find a place that uses methadone i went to white deer run in allenwood pa.
I did an outpatient detox, but I would imagine the meds are similar. They won't give you anthing with "street value", a.k.a. anything that is potentially addicting. A common med is clonodine, which is a blood pressure med and helps a LOT! It's uses also indicate that it helps with withdrawal symptoms associated with alcohol, opiates and nicotine.
I also received another med (cant remember the name) to help me sleep.
They would likely issue you immodium AD as well, to help with diarrhea/GI issues. Also, they would probably start you on an antidepressant such as prozac or cymbalta or paxil or something.
they will give clonidine (helps with restless legs but that is about it really), yeah, immodium, probably a nerve pill (benzo) maybe anti depressant then it is really pretty much cold turkey. they are a big fan of cold turkey. at least around where i live.
