I did in college. It was a freaking great and amazing time(until it ended). Seeing flying frogs in the dawns early light was rather odd. The curtains in my house were dancing to James Brown. I laughed my ass off for 2 hours with my friends. The whole trip lasted about 6 hours, then got all speedy and made me feel terrible. Tried to sleep, nothing helped. I drank a gallon of cranberry juice, damn near shit the bed. Finally my body and brain crashed the fuck out. I slept for 20 straight hours. As I look back on it. I would never do it again. I do think it has actually helped me become the weirdo I always wanted to be. Peace and Love! Weed and Beer are fine! Fuck the hard shit!
