Welcome to NeuroTalk.
You experience is very common. The drinking is a common PCS problem. The concussed brain is very sensitive to alcohol and the toxins in alcohol.
You should consider making two changes in your life.
First, no alcohol for a few moths. When you are feeling better, one serving per day may be tolerable. Avoid all alcohol if having a single drink leaves you with a hung-over feeling. This is highly likely to happen.
Second, You need to stop any contact sports or other risks of impacts to your head. You may be more tolerant after a year or two.
There are more things for you to consider but this will be a good start. Others will likely tell you about their experiences.
When you are symptomatic, you need quiet rest. B vitamins will also be good.
So, take it easy and learn to live a more disciplined life. Your brain will thank you.
My best to you.

59 years old, retired due to disability, married 34 years, father of three, grandfather of four, Suffered a serious concussion at 10 years old (1965) stopped most driving after concussion at 46 years old (2001), Post Concussion Syndrome/Multiple Concussion/Impact Syndrome with PTSD, immediate/short term visual and auditory memory problems, slowed processing speed, visual/auditory processing difficulties, insomnia, absence seizures, OCD, 14 concussions since first concussion at 8 years old, Taking paroxetine for 14 years and gabapentin for 12 years. Added L-Tryptophan and stopped paroxetine after 3 months of tapering. I currently take 500 mgs of L-Tryptophan AM, 500 mgs noon, and 500 mgs PM.
As of Nov 15th, Due to high stress issues resulting in PTSD, docs put me on 3 meds. Clonazepam but only for 30 days ) .125 mgs twice daily (Doc presc. .25 mgs 2x daily but half a tablet is good) , citalopram (Celexa), an SSRI , and olanzapine (Zyprexa), an atypical anti-psychotic that usually causes weight gain before bed. I lost over 30 pounds since mid July. It just stopped the weight loss. Took me off the gabapentin. I am feeling better than I have in years.
This great feeling only lasted a month. Back to the same old PCS doldrums.
May 2014, I am off the olanzapine due to a 6 fold price increase. Back on 600 mgs of gabapentin before bed.
I am also taking L-Theanine to help with GABA regulation
