yea same here, ive managed to do 7 hits of 20x though in a row, my friends just kept loading the bong, and even though i didnt know what it was or who they were, i thought i needed to keep smoking it so i ended up doing 7 hits of it. basically i died and was reborn in my trip which was a pretty intense experience. i would compare it to the affects of nitrous mixed with a large dose of mushrooms and weed.
