GHB question?

dont say rape because i already know that i just want to know..how long does it take to affect you? and specifically what happens. i know you go insane. how long does it take for you to pass out? are you conscious and able to talk? and say things you wouldnt normally say? does the amount given to you affect you differently? i was given this at a bar. i was standing up and i remember falling flat on my face and someone told me this. and then i ended up in the bathroom and i remember acting really really crazy and psychotic moving my arms, my feet, moving alot, my mouth, clapping my hands and stuff like that and i couldnt keep my eyes open and i remember not being able to move..like how you look when you are on ghb..and then i passed out. and then i remember waking up and saying what happened because it was obvious i was raped. does this sound like ghb? please tell me as much as possible. and is it possible for someone to give me something like a pill so it doesnt show up in my
blood?
going to the hospital has already been done etc and the rape kit i just need to know about ghb
