If you are going to do acid make sure you are with good friends who you trust so you dont freak out. Expect to be trippin for a while, my first time I freaked coz the trip just kept going and ended up being roughly 10 hours of trippin. Make sure you think positive thoughts when you are waiting for the trip to kick in, dont freak out and think "what if" or "should I have done that"...just take it as it comes. Also you'd want to have some experience with pot so you have the stamina to maintain calm...

Good luck
