Something that might..well..sensibilise you.

I don't drink hard alcohol or wine anymore, only beer (MEAD!)

don't do drugs anymore, either, I'm already out of step with the rest of my fellow employees here at Dept. of Defense. but one thing is for sure, LSD will open your eyes. Do it with a friend who has been there before, have lots of good music ready, and a pen and paper. Shrooms are cool too, a more mellow high than the chemicals.

but hey, if you're already tripped out naturally, then more power to you.
