Mushrooms felt less "chemical". I'm not sure how else to put it. Like side effects of medicines...if that makes sense. Or the way a chemical burn feels. The LSD hangover felt that way...just wrong. I got dosed by a swimming pool's chloride feeder one time. The residual feeling afterward was that way. You could almost feel the poison coursing through you. I didn't much care for LSD because of that.

Mushrooms felt cleaner, I guess. I'm way too high strung to do either one now.
