Last weekend i went out on the good green question marks. (tested them straight to black). Had a fantastic night and ended up taking 2.5 of these. Was rushing like maad all night. At about 11.30 in the morning, just as i started coming down I nearly passed out in the club. I was looking at something and then i moved my head and the first image seemed to stay in my head. It was though my brain was working two seconds behind my eyes. This freaked me out big time. Had to snap myself out of it to stay conscious. About an hour later i really started freaking out big time. Feeling as though i was out of my body. I could not focus on anything and had to keep moving around to stay conscious. I had never been so scared in my life. This seem to wear off but then i started to freak out later that night and decided to go to hospital. In the end they gave me some valium to put me to sleep. I went home and slept it off. Today i am still a bit tired and scattered. Just wondering if anybody has experienced this or has any explanation. I am not a heavy user, go out probably once a month.
