I have a friend who would indulge a little too often and one night he kind of overdid it. I remember him taking pictures of strobe lights and and rubbing my carpet for a couple hours, it was all funny watching the fucked up kid at the party but the next day shit hit the fan.
He was always kind of a weird dude but now he can't be left alone, he's like an infant. At night, it's not unusual for him to sneak off and go buy everything at a gas station.. I'm talking food, sunglasses, stupid hats, you name it. The doc say there isn't much that they can do, which isn't really surprising, but he has been getting better lately on his own.
You never think it'll happen to you but drugs can mess you up, never take them lightly, if at all.
