This thread has some incredible stories in it. A+ for starting it.
I can't think of anything as scary as most but..
-This one time a friend and I were taking temazepams and Norcos (hydrocodone 10s) by the handfull and I kinda blacked out but was still awake, after a half hour of just a memory blank where we apparently walked across a large busy highway to meet a friend with a quarter of bud, I kind of wake up to reality to see myself leaning over our homemade bong ripping on it. I had no idea what was going on really but just kept hitting the bong when it came to me.
-Wake up after ODing on vodka at a DMB show (I never made it inside

) to nurses and doctors all around not knowing what the hell is going on, lying on a stretcher in the hallway of a hospital, convinced all the staff workers were hispanic or only spoke spanish and kept yelling in spanish to them, passing out again and waking up to my parents next to my stretcher telling me about my BAC of .283 blahblah. It sucked.
-Halloween I was doing an inordinate amount of drinking and smoking, came home, made it to my suite/dormroom fine, I remember that, but waking up at 7 (3 hours later) 3 floors down in a suite of 4 girls, in some girls bed (she wasnt in it though) not knowing where I was or how the hell I'd gotten down to the 8th floor. To this day I still dunno why I ended up there.
- Also this year, probably my second college party, I was also mildly addicted to klonopin at the time. Go to a campus of a university that shares some campus space with our larger university, to one of their frat houses. Anyway, I wind up meeting up with the same dealer I bought a gram off of last week. I was drinking alot of beer and my memory was fucked from the clonazepam anyway so I guess I bought weed off him. I sold some ambien I had, smoked a blunt with some dude and did the similar thing to above, kinda blacking out without passing out and 'waking up to reality' in someone's dorm room, sitting around a hookah filled with weed, lots of people in the room, being handed a bottle of rum and drinking it. Not sure how I got home that night.
