Abstract
My first concussion was in 2012 playing football. I took a big hit, was disorientated and confused, but recovered quickly. I went out drinking with friends the next day and played, symptom free, the following week. A year later I was involved in a scuffle while intoxicated outside a club. I received a blow to the back of the head, vomited for the next 48 hours and had headaches for a week. My symptoms then resolved and I thought no more of them.
