Damn, man, that sucks shrooms are fucking fun too. I can't do them anymore because they just take me back to this bad trip I had, but I wish I could. Maybe have a talk with your brother about mushrooms. Tell him the purpose of your trip, and why you want to do it, and whatnot. Maybe ask him to trip with you, even if he's not a drug user, a mushroom trip is something valuable to all.
