Replying to concussion

So yea i gotta concussion friday night after trying a corked 3 over a small table. I remember the inrun, goin over a roller, and then waking up on the slope having Pee Skatrol asking me wut day it was. My friend says i was knocked out for 5 mins drooling. Had to get the ambulance ride and all that ish. doc said no skiing for a week. my question is when can i seriously start skiing, and would consuming large ammounts of alchol hurt my headaches ne more or fuck my head up? thanks.
