Purely out of curiosity, which drug is this, if you don't mind me asking?
Sodium oxybate. Active ingredient is GHB. I was stunned to find out this was a therapeutic but apparently it was developed for potential therapies and was only coincidentally discovered to be intoxicating. I used to suffer debilitating cataplexy and sodium oxybate has nearly wiped it out.
For me it's amphetamine. I have severe dehabilitating ADHD-C and lisdexamphetamine has completely changed my life.
