ha. my buddy and I used to choke each other out in the basement laundry room (ifyouknowwhatimeen)after hearing about it. it was fun the first 5 or 6 times and then I believe we moved on. I remember liking the distinctly peculiar feeling I'd get upon coming to, after being passed out for 5 or 10 seconds. At first as I woke up I'd have no clue where I was or what was going on, and then as my brain put it back together I'd get this surge of happiness. I'd say this was the closest thing to my first true notable drug-like experience. I hadn't even started smoking cigs at that point- I think we were in 6th or 7th grade.
You need to hyperventilate for a good minute or two before you breath in deeply before you cut off the arteries.
