ultra strong sleeping tablets wanted UK + advice

Hi all!

Need some advice on behalf of my wife. She broke her back 3 years ago and has suffered with pain ever since and sleeping.

We went to the states and she was given some Roofies, Flunz-pam something. They were white with a cross on. Unsure of dose, but they were strong. She had a couple of drinks on a friday, took 1 1/2 or 2 and then fell asleep quickly without pain.

She was alittle hungover the next day but recharged her batteries enough to deal with the pain.

I have tried several sources in the UK to get these exact ones and failed. She has tried others and they have been no use, poor quality or I've paid and nothing has turned up (i.e scammed).

Shes getting totally fed up now and everything the doctor gives her doesnt compare.

Can anyone suggest where I can get similar ones from??

Really need help on this one....
