Definitely MDMA, every time has had me puking my guts up. One time I started coming up, got the usual nausea so I set off to the toilets to puke up, when my vision went all blurry, I couldn't see at all, was drenched in sweat. As I couldn't see I just started puking anywhere, a bouncer came over shouting "PUKE IN THE FUCKING TOILETS YOU CUNT!" Haha. My mate literally had to drag me to the toilets, then when he saw what state I was in started making himself sick cuz he thought it was dodgy md! Ten minutes later I was raving my tits off
