recently I've been listen to I doser and such, it really helps me get to the falling feeling and the vibrations. the only problem is after 2 -3 minutes my eyes roll hard to the back of my head to the point were it hurts a bit I cant tell if there shooting back and forth or just trying to slam and far back as they can. alot of times after a minute i make it stop, im worried though that by stopping it it causes the process of SP to stop, this happens even without the music. any idea?
