All the kids around here hunt for mushrooms in other peoples' closets and under their beds lol (these kids have more tupperware than Martha Stewart).
Anywho, mushrooms can definitely be more relaxing than acid. It doesn't matter how seasoned or tolerant you are, if you take too many strong doses you can easily bad trip. I had one friend get his tongue puddled with about 20 drops and it made him temporarily psycho. He was even institutionalized for a short while. The guy was in a near-paralytic state while trippin' and wasn't capable of speech. He had also been doing acid religiously prior to that experience and his tolerance was up, but it wasn't enough. To those of you who think bad trips are just a product of bad environmental factors, I must say you are wrong. There is a certain scariness that sets in when reality completely fails you, and 3 hours into your trip you realize it's only gonna get more intense and last for about 5 more hours. All in all, acid is what you make of it (meaning-wise)... It's a false sense of connectedness and understanding. I had the whole universe figured out once, and a few hours later, I couldn't even remember it. After so many trips you begin to realize the euphoric feelings and awe-inspiring realizations are so fake that it's purely a recreational mind/time killer. Not the worst way to spend ~8 hours though (definitely not the best either).
