I've had a few bad experiences.... I guess that's why I decided to stop... First I had that when I hadnt rolled for a while, when I started rolling again I would get panic attacks that the pills were actually rat poison or something. as a result I heaved up everything I'd had to eat that day, and for hours on end, til there was nothing left... This happend to me at Sensation, 4 elements and a bunch of other big parties... Was pretty sucky cause it ruined those parties.... After I got that in control all was good... Until the last time I rolled.... I was at a party, and due to lack of sleep the night before and the combination of E and heat etc all of a sudden I started to get disoriented. Like when I'd blink, when I would open my eyes I wouldn't know where I was or what I was doing, I started to get super dizzy. I thought I was going to faint seriously... I don't remember half of that party... and then I figured my body was telling me it was time to stop, so I did
