Everyone who has asked me what its like and if they should take it, i always say yes, but it is 100000% important to make sure you are in good surrounding, friends you trust and so on. if taken like this then you can unlock a completely different world where anything you want can happen, a place where your sub conciouse ( sorry very dyslexic) mind shows you what it wants.
there are no physical side effects.... unless you have a 'bad high' this can happen if you have something troubling you or you are around people that you dont really trust/like. and you could end up seeing not very nice things, I cant stress enough how important it is to be in a good mood and have an open mind when taking acid/LSD.
acid trips can last upwards from 15+ hours i had one that lasted for 20 hours- amazing weekend plus at a fiver for a tab thats a bloody cheap way to spend practicly a whole day.
VERY VERY VERY IMPORTANT!!!!!
with other drugs the more you take the more high/stone and genreally mashed you get, but with acid its not - you dont trip more (well maybe just a little) you trip for longer.
If you are worried about taking acid/LSD i would highly recoment trying magic mushroom first, then you can get to grips with tripping get to know what your own body feels like when you trip (and im not talking about touching your self(although haha fun) for example every time i take acid my knees go numb haha. everyone will have their own reactions.
The trick it just to have an open mind, dont worry about taking when you take it, just go with the flow and if you feel uncomfortable at all tell someone so they can keep and eye on you, because i dont think people would take kindly to you licking them thinking they are food! haha
hope this helps.
