hmm, I guess there aren't any sources to say which is true. Timothy Leary's autobiography has a pretty decent section about his first dose and it seems to be a dose of quite larger than 250 mics but ol' timoteo could have been exaggerating a bit. That's too bad, that was one of my favorite parts of the book, and kind of legendary details about his life imo. I read his autobiography at the ripe age of 16 or so, so I looked up to him a lot even though a lot of people consider him a fraud of sorts 8)
edit: and as for how this post has anything to do with the actual OP's post...
I'd like to meet someone who's taken a huge dose of LSD like over 10mg (a sheet theoretically) and just see the way they talk about it haha
I guess you could say i'm 'weird'
