I've recently run across some mp3s of Allan Watts speaking about his trips with LSD and you might want to check them out. Also if you haven't, you may want to look around
http://lycaeum.org/ and
http://www.deoxy.org . The last looks horrible to me, but I've been entertained alot by the trip reports and alternative philosophies presented there.
I would highly suggest a sitter for any psychotropics you may decide to try. As much as possible try to make sure you are getting high quality drugs, and not some inexperienced cook's random chemical cocktail. The way your teeth feel loose and the other dirty feelings from some bad acid isn't something I'd wish on anyone.
Best of luck, would love to hear back about your trip if thats the route you choose.
