I took them a couple years ago, and man, was that night trippy. We were trying to make a flashlight battery burn longer by giving it grass to feed the flame, haha. Then, I got stuck with my best friend on this huge bed because it was dark in the bedroom and the bed is high off the ground and it's almost like we were stranded on a desert island. Not many cool visuals though, so I was disappointed.
But as to the question on whether or not it changed my life... I would have to say no, because after a couple days I wasn't even thinking about them anymore. No withdrawls or anything like that. I wouldn't do them on a full-time basis though, because why tempt fate.
