Here's an old hubski post where we talked a lot about acid :
http://hubski.com/pub?id=37345 And here's one of my comments in that thread, to someone who was considering their first trip :
"This is not a decision to be made lightly (IMHO). If you do decide to try it, be sure that you are in a safe place, with people you can trust. Preferably outdoors, in good weather. Avoid travelling, for your first time at least - you don't want to be trapped in a car or a bus, for example. Don't panic. Listen to music. If you are lying to yourself about anything in your life, you can expect to be reminded of it. It can be scary. It will probably be lots of fun, too. You will get a weird, unpleasant sensation in your gut when it starts - that feeling will subside, as it kicks in. Once it starts, you just have to ride it out, there's no way out except time (and you might feel like time is not passing at a normal rate). It's not like other drugs (well, except for mushrooms and mescaline - it IS a bit like those)." [edited to add this shout-out to BLOB_CASTLE]
