Sleep aids
Is Zolpidem approved for aircrew use in the UK? From a simplistic, non-medic, view it seems to be a better thing to use than Tamazepam (which, I think, is approved) because of the short half-life and short time to time to take effect, plus it's approved for use by US military aircrew.
What about Zopiclone?
I've looked for a list of approved medications but without success - any hints on where to find it?
