I doubt you would even be able to get a prescription for pentobarbital/Nembutal. It's a Schedule II narcotic. I think it's mainly used for sedation in the hospital and for euthanizing animals. I had a friend who worked in an animal research lab and they used pentobarbital to euthanize lab rats. It's used in assisted suicide too. So, it's pretty tightly controlled.

When I was talking to my mum about my depression back in the fall, she told me to ask my doc for phenobarbital. LOL. She told me she had "baby blues" in the 60s and her doc gave her phenobarbital and it made her feel "wonderful!" Docs don't hand out scripts for barbiturates so readily these days, though. I think that's a very good thing. Once the benzodiazepines came on the market, they took the place of the barbiturates because it's much easier to OD (even accidentally) on barbiturates and they're more addictive than the benzos.
