I know this was mentioned in a different thread however I was wondering if being under the influence of alcohol (consumed alcohol) when the time of being concussed has an extended impact on Post Concussion Syndrome?

To this day i still deal with sleep problems, fatigue, and tinnitus. 2 years after a bad accident. Although certainly better i did not dream that symptoms would persist for such a long time. Hence I believe that alcohol might have altered what might have been a quick recovery had i not consumed anything the night i was concussed.
