Is black out common when you intoxicate yourself?

Tweet

Ok so I know this is an odd topic but i am kind of worried about my well being. I've never blacked out after drinking alcohol but this happened at a friends house. Between 6 people we finished a handle (not a bottle) of Crown and yes it was a ridiculous amount, but i unconciously drank it even though i have no memory of it. After waking up i found a pool of puke on the floor and on my pants, and for some reason my forehead started hurting. It wasn't a headache either. i sloppy head for the bathroom and my tail bone -_-?? started hurting. i was thinking to myself OMG what the heck happened? i looked into the mirror i found bruises on my forhead and on my cheek as if i got into a drunk fight. I was shocked and my friend said i was one crazy muther****** last night. Supposedly i unconciously banged my head against my friends and he got mad so he head banged me back which explains the bruises on my face. Then i head to the bathroom and i slipped and fell on my butt which THANK GOD explains my tailbone hurting and i banged my face against the toilet. I feel like this event as a series to "Hangover" but funny thing is it only happened to me.. So what is your story??
