dude that sounds like it might have been mentally related cuz when u distracted ur thoughts u were ok, i had the same thing happen to me, my friend and i smoked 3 bowls of some of our stuff, then a friend brought in some northern lights and we hit 2 more bowls and i was laying on the floor completely fucked over, it was crazy i was coloring those fuzzy posters that u cant mess up on, which i highly recommend man they rock the bright colors r soo cool but ya then that night was hell, i dint eat anything cuz i dint feel like it so the munchies got to me and destroyed my stomach then that same night i caught a summer stomach flu and was throwin up all night, still a good trip tho, but ya i dint like my high at the time either until i started coloring and then it was awesome, im a damn good colorer high too
