Last time I did any salvia, I think it was like 37x, I was by myself (dont do that) I hit it hard, and fell back onto my bed, the first thing I felt was like my vision was stunted and if I wasnt focusing on something, tv, a picture, etc, my vision would blur away. And I guess to combat this I closed my eyes and put my face into a pillow and felt like I was pushing my face through the pillow, then I was trying to stand up and started to get real hot and kinda sweaty, but in my head I could like feel the pours (sp) of my skin opening, and the sweat coming out of each pour, shit was crazy, after that I kinda got sleepy and dont remember anything else specific, then I was cool, shit only lasts like 20 minutes.
