Ag too many to make sense... but trust me it is most "fun" the first time... it can get pretty scary too... if you don't get scared that you took too much and that its never going to stop, then you took too little. The best part is always just as you break through the fear bit, which I suppose is a very internal thing... The bigger hiding you deserve, the bigger hiding it is going to give you.. it is a very fair drug. If your house is in order it will treat you like a god.
For your first trip, I suggest haveing it at someone's house... with a few friends... no going out, and noone, not on the trip, with you. Get some nice disney or other cartoons, I used to love aladin, but I think Wall-E would also be nice... watch the movie while the trip sets in, and then again immediatly. This should take care of the first 2 to 3 hours... by hour 4, you will likely feel a little crazy (in the men with white coats way). By hour 6 you are nerly fine again, but I would still hold off on driving for the day.or at least for 8 hours. Driving on acid is not like like driving drunk... tree trunks suddenly swell 3 times their widths, cevron signs get new meanings, and the stupid distracing fires burning everywhere in the corner of your eyes... makes everything look bright and christmasy... you WILL forget you are driving....
Buy alot of beer... you are basicaly imune to the alcohol to a lerge extent (well weed also), things taste and smell diffirent on acid... asif your nose gets much stronger... if you smoke you may suddenly not be able to stand the smell of the packet from a an arms length for example.. that sharp... Beer is quite drinkable... coke gets yucky quickly... Its also nice to have an assortment of sweets, you are going to look for stuff to CHEW, till your jaw hurts.
I took my first acid without knowing what it was, what it will do, or any guide... I had to figure it out on my own... man oh man oh man... I still have to forcefeed it to myself to take any...but I have a great fondness for this lower level teacher.
I think high quality LSD should be your first trip before trying salvias and all those higer level ones... they will not let you see shit until you are ready... LSD will show you that you are ready, there is only the option to take the next breath or die.
