I have eaten shrooms, and dropped acid. The shrooms will go away in one night, granted you didn't eat like a whole once or somthing. the high is soo cool, like the walls breathing,and patterns moving. while acid is a plundge straight into insainity, visuals are veary strong, colors and patterns stand out more, the only thing i hate about acid, is the next day your down. like you broke your head . if some one was trippen for the first time i would go with an1/8 of shrooms eat half, nothing in half hour, eat the other half. you shouldn't get to to crazy, and always have a safe sitter. someone who's gonna tell you "shut up, your just trippen, and look at this."
