this man seems to be the only educated man on this thread, i think atleast 90% of people who trip mistake movement of consciousness through your body for a medical condition which for most is always deemed a bad thing. like whoever wrote about their leg trembling when tripping.... god damn newbs.
plus whoever wrote the response about acid junkies being strange, learn to see reality in different lights and tunnels, those weird people may just be the future of human evolution.
for all you " oh i used to trip and i had my fun with it, just dont want to go to far out" people remember this, when you are tripping what you are tripping on is not the chemical of lsd itself, actually your tripping on what medical doctors call your BRAIN!! lsd acts only as a catalyst or a key if you will, it doesnt stay in your body for more than one day. Also what lsd does to your brain chemistry is it opens and fires new neuronal pathways that which previously were either dormant or nonfiring.
SO in essence if you want new processes happening in your brain which can lead to new realities, new thoughts, new perceptions, new beginnings, go for it. but if you like yourself and your normal conscious operations then dont take acid.
