Had a major surgery in Japan that required general anesthesia. During recovery, the only pain killer they would provide was loxoprofen (ibuprofen). Naturally, this didn't do much, and I couldn't sleep through the pain. But thankfully, I was given a prescription for brotizolam quite readily - - a powerful and abusable hypnotic used for sedation...
Anyway, still gotta say thank you to the doctor that put my knee back together! Also, with insurance the total was less than $1,000 and my drugs were a few bucks -- don't even want to imagine the cost back in the US.
