Cataplexy or not…Xyrem by jazz pharma. They just approved one for kids. Its GHB. You can only get it from one place and its highly controlled but when Xyrem is used for medicinal purposes, such as narcolepsy, it is classified as a Schedule III controlled substance under the Controlled Substances Act. However, even if you obtain Xyrem for medicinal use, but then misuse it or offer it to anybody else to use, then it is considered a Schedule I controlled substance and illicit use is subject to Schedule I penalties. There is now “idiopathic hypersomnia” basically we don’t know whats causing you to be tired all day even though you might sleep at night. It is effective and safe at the prescribed amounts and metabolized by the liver into CO2 +H2O. If someone was to take it wrong or with ambien, or Gaba-A drugs, ETOH, it becomes an asshole. but one of the safest meds out there. If you are having this big of a problem , all kidding aside. This will work.
