we had been rolling at a festival since 10 am. it was about 9pm and i was still stupidly popping doses. My buddy had bought a bottle of formaldyhyde (the moron thought he was buying hash oil, dont ask me how he confused it). anyways, it was in a water bottle. none of my friends had ever been around the stuff so they were smelling it (not to get high, just cause it has a very unique smell, kinda like death!). the bottle was passed to me to smell, but i was rolling so hard that i wasnt paying attention. i thought i had a bottle of water and took a big drink of it. my mouth felt like fire instantly. i only swallowed a bit, but it was enough to start me vomiting. it had eaten away at my tongue (i still have the divets) and i was puking up blood, turning blue cause i was gagging and couldnt breath. eventually on-sight medical staff got me taken care of. lots of water and milk. i couldnt talk for a couple days and didnt eat much (just jello, noodles etc) for about a week. i thought i was going to die. really changed my whole perspective on what i was doing to myself. but i laugh at it now.
