My friend has oxazepam from earlier this year that she no longer uses. I slept over and didn't have my Xanax on me so figured that it's also a benzodiazepine, so what's the harm of trying it?

I took it quite early in the evening and it hit me harder than Xanax or Ativan has ever hit me. I was so drowsy, quite dizzy and apparently slurred a bit.

Has anybody else ever used this drug?
