I've tried agaric on 3 occasions. Keep in mind that I really don't like psilocybin 'shrooms in the first place but amanita is even worse in my opinion. As opposed to LSD and Mescaline; shrooms always make me feel weird, paranoid and out-of-place. I love to grow them and share with friends who enjoy them but they're just not for me.
Amanita Muscaria Sucks. I'm sure that many people can gain some insight from it but it's not something that I'd recomend over psilocybin.
On the occasions I ate the caps it was very unpleasant and I won't do it again.
Amanita contain muscimol and Ibotenic acid. When you cook them ( bake 'em in an oven ) the ibotenic acid converts to muscimol. This is a good thing. If you're going to eat them, cook them first.
However, they also contain muscarine which doesn't go away or change when they're cooked. This is what causes you to sweat like a hooker in church while you're freezing you're ass off.
All in all, I think amanitas are garbage ( and I wouldn't even want to try Pantherinas (death cap)). The only hallucinations I had were auditory. People talking behind me when there was no one there, music playing, crickets chirping. Mostly I was terribly paranoid, sweaty, confused and nauseaus. And those were all fairly low doses. If that sounds like a good time to you then knock yourself out, but compared to psilocybe shrooms they're definitely not as fun.
