Replying to Dr. ns help meee

hey so i've already searchbarred and i haven't found anything that fits my situation.

i was skiing tonight and was doing a 1 [don't laugh at me] and i couldn't see the landing cause it was dark, and i fell and hit my head pretty hard and didn't get up for quite a while. i was wearing a helmet. so after i was mad dizzy and my head was killing me and having a little trouble seeing shit for a while. now i can see and im less dizzy but my head is pounding. now before i was drinking all day and was pretty drunk and hyped up on caffeine, so thats probably not helping. 

so anyway how do i treat this cause i want this pain to go away so i can sleep tonight. or should i not sleep cause i heard that you don't want to sleep after you get a concussion? i heard its also not good to take pain killers cause you can clot or something?

btw this is my like 3-4th concussion, and i get immediate headaches if im tapped too hard in the back of the head. i've already been to the hospital for a concussion and got a cat scan and they said my brain was fine. don't really want to go again, i have shit to do tomorrow

someone tell me what i should do?
