I hit the last plateau on accedent a few weeks ago.
I took a whole bottle using Delsym method. I smoked and felt pretty fucked up, and started to get nauseous. I went to the bathroom and felt the need to lay on the floor, and as I was a burning sensation rocked my body, and felt as if I was floating out of my body, it felt like 5 min., but I was there for 20. My friend checked on me and brought me to bed. I couldn't walk. Everytime I closed my eyes I was somewhere different, the mall etc. The burning continued, and the world around me kept tricking me, I thought people were everywhere. I threw up a lot, and evwrytime I did I was sober for a few min, but it came back. It lasted all night. Haven't done it since.
