yeah, chlordiazepoxide (librium) and diazepam (valium) are common choices, but it depends on the clinic, in the first detox i was they used clonazepam mainly. i personally find clorazepate to be the best choice, but that's just me personally.
but this is besides the point.
every benzo withdrawal should be handled the same way: controlled taper + anticonvulsants, the clinics i've been to favored sodium valproate or carbamazepine for this, although gabapentin was also used.
edit: i did a cold-turkey withdrawal at home once, after a three-month flunitrazepam/alprazolam habit, taking ungodly amounts of them daily and IVing them too quite often. what can i say, i was 19 and dumb. don't do this. even if you don't get a seizure (which can kill you, grand mal seizures are nothing to take lightly) it will be excruciatingly horrible. even with a taper it's gonna suck, but not nearly as bad. also i had both gabapentin and sodium valproate at my disposal, otherwise i would have checked myself in.
benzo WD really is serious shit.
