A tip I've heard: once you've dried your mushrooms, put them in a glass jar with a silica gel bag and wait 2 months. This so-called curing supposedly converts more of the ibotenic acid into muscimol.
Don't know how true that is, but seems to work for me, as the aged mushrooms are less nauseating, or maybe it's the ginger tea I drink them with? In any case, it's a much more pleasant experience compared to uncured mushroom. At the doses I've tried it's mostly physical - a sense of lightness, like flying, analgesia and invincibility. At higher doses it may become interestingly psychedelic.
