And I thought I was the only one...
Knock yourself out... er, bad phrase.
Do GHB to your heart's content (there we go), but please, please, please keep it out of the clubs unless you get the powder form and know your limits VERY well.
Why do I say this? Because I have a habit of dumping water all over the crotch area of mother fuckers who pass out from GHB in clubs. Falling out assholes are bringing intense scrutiny to the clubs from police. So, if you don't want it to look like you just wet yourself, don't fucking pass out in a club that I may be at.
