New, another stickler for spelling. Sigh of gratitude. Anyway, back to the NHS and meds. They have just about everything here that they do in the States. They're a lot more reluctant to dispense some of the "harder" drugs, such as those with an opiate base. I have a chronic, very painful, and progressively debilitating joint disease, and take OxyContin for it (the same drug that Rush Limbaugh got in so much trouble about, and that Jack Osbourne went into rehab over, in the States). If misused, I'm sure it can be addictive (actually, I suppose it's addictive, anyway--but if misused, I guess you can catch a buzz from it). Here, local pharmacies have raised an eyebrow or 10 when my husband has gone to them to fill my prescription, and it often takes going to five or six pharmacies to get the prescribed month's supply (you'd think you were asking for heroin and a syringe). But the price remains £6.40 per prescription, and I can only imagine how much more it would cost in the States. Anyway, if you give your GP the generic name (for example, Valium's generic name is diazepam), he'll prescribe what you've been taking in the States.
