A multi-vitamin will be far short of your brain's needs. You could add a B50 or B100 complex to the multi.

The alcohol issue should be a serious consideration for your lifetime. the research shows that a limit of a single serving per day is OK but no more. Think of it this way. Your brain will now be very susceptible to future injuries. Getting drunk impacts your brain similar to a concussion. The hang-over is your brain responding to the toxins in and from the alcohol.

My neurologist who treated me in 1970-71 when I suffered some long term PCS symptoms warned me to stay away from alcohol for life. He was way ahead of the research. The one time I drank a large glass of beer, I had a miserable hang-over or PCS the next day. Just one beer. There was till plenty of pizza but the soft drinks had run out so I tried the beer. Big mistake.

Please consider your martial arts a serious risk for another concussion. The next one will take much less intensity to cause damage.

But then, You are young and part of the "I'm invincible" age group.

I hope you don't learn a serious lesson the hardest way.

My best to you.
