Well, i'm so fucking sorry for my lurking. I guess I did not feel I had alot to add, due to my relative inexperience.
Still, i'm trying to get into it, with a bit of help from generous people like Tripitaka.
As for things I've eaten, I once foolishly tried datura when I was a teen, before I even knew how dangerous it could be. I had read a book about Shamans so I just went out, found a Datura, and ate some. I actually thought it was enjoyable. My friend on the other hand, had a bad trip, and kept on babbling about how he could only see in black and white.
Umm that's about it.
