First, stay off the alcohol. Maybe a beer a day maximum. A hang-over is the brain's toxic reaction to the alcohol and its metabolites. Your brain is very sensitive to toxins.

There is some research that indicates that relapses (decompensations) of symptoms are a step backwards in your recovery. You want to avoid any activities that cause a return of symptoms. Otherwise you will find yourself on the roller coaster of getting better, getting worse, over and over again. The roller coaster can lead to serious depression not to mention mess up your grades.

There are plenty of students who have active college social lives without alcohol.

btw, were you ever a binge drinker from time to time? Especially as an adolescent? Research shows that adolescent binge drinking leaves your brain much more susceptible to later struggles, especially with alcohol. The adolescent brain is too busy trying to mature to tolerate the assault of alcohol.

I lived through decomps during college and know your struggles. It only took one beer to tell me how sensitive my post concussion brain was to alcohol. I was a mess the next day. My brother related later to me that he could tell that I was hung over. Wow, just one beer.

My neuro when I was a high school sophomore and having serious cognitive problems and absence seizures from a concussion during soccer had warned me to avoid alcohol.
