*while I haven't done LSD in a long time [I haven't done any drugs except caffeine and nicotene for a long time], it was the drug I enjoyed. What I *didn't* like is that it lasted TOO LONG. 8 freakin' hours. First 4 were great. But then, I had to go into the office the next day.. or school [depending how old I was when I did it]. and was annoyed I couldn't sleep. Also, it's the only time in my life that a cheese sandwhich could taste and feel like plastic and cardboard mixed together. Almost not worth eating it tongue emoticon It's probably the only one I'd recommend but ONLY IF someone is in the right mental state for it. It amplifies and if you're not psychologically healthy, don't do it. It doesn't really *add* much to the brain per se... it just messes with the dials a bit, turning up some chemicals while inhibiting others. You can have a similar effect by not sleeping, or listening to certain music, or whatever. The drug just kinda guarantees the SpecialFX. That's awesome. You can develop synthestheia.. at least I think you can. I've been told I have it, but I'm skeptical. I see sounds, feel colors sometimes. Smells have texture. But these are all things embedded in our language as well through metaphors, so I suspect we *all* have a form of synethesia. [a word I can't spell tongue emoticon ] I was like that since I was a kid. The world has never been dull to me.
