Checking to see if you made it thru the night twizliz???? Hopefully eveything turned out okay. It's pretty hard to give yourself a concussion. I know because I am a MAJOR clutz and have wacked my head very, very, had on many, many, occasions!!! Sad, but true. I'm surprised I don't have serious brain damage it's happened so much. And out of all of that I have only had one concussion. Symptoms were, bad, bad headache, slurred and mixed up speech, lack of coordination ( could not get the cap back on my bottle of water at all!!!), and other stuff like that. Hope you turned out okay!!!
