How to enjoy benzos?

I've got a big stash of Xanax and Valium (generics). I've only tried the Valium and usually to put me to sleep before airplane flights or after MDMA. Other than a good rest, I've never gotten anything enjoyable out of it.

What would be the right way to use these drugs recreationally? Otherwise, I'll just save them in case of a bad LSD trip in the future.
