well, the first time i did acid was alone in my room. I think it was one of the best ideas i have ever had. all my friends advised me otherwise, but i made up my mind to just go for it, and it was an extremely positive experience. however, i do not reccomend this for everyone. this worked out well for me because i am naturally more introverted and i have a strong sense of self, and am very grounded when i am alone. the experience gave me a lot of confidence when i realized i had basically come face to face with a complete disappearance of ego and did it completely alone. it made me a stronger person. some people would not be able to handle this however... it takes a certain attitude towards life... and you can see it in most people. some would have an impossible time with the disappearance of their ego because they rely so heavily on it... others would get through it fine because they don't have a 'symbiotic' relationship with their ego.
