The interesting thing with benzodiazepines, which activate inhibitory activity in the brain. If you are very anxious, it might improve your hypnotic response a bit. If you're just so anxious and [indistinct] you can't do it. If you're not very anxious, it actually inhibits hypnotic activity because you get sort of sedated and just out of it. And you can't focus your attention, as well. So, by and large, we don't use drugs as an adjuvant to hypnotic experience.
