I never get that bad, only time I ever blacked out I downed a almost a liter of vodka and topped it off with a well-carbonated beer. I felt fine until the beer hit and I blacked out, woke up hours later on the couch after puking my guts out for about 5 hours, thankfully don't rremember any of that. Hangover was mostly just gut rot from the excessive vomiting, but somehow my hangover wasn't too bad. No headache to speak of, no vomiting either, no light sensitivity. Feels good to be 21 man, won't last forever.
