I have Cerebral Palsy which is a brain injury, and have officially banned myself from drinking because I saw my friends who also have Cerebral Palsy get drunk at a party and the results were bad. A tiny bit of alcohol seems to have a much larger effect on people with brain injury because they acted horribly and some injured themselves and had horrible intense hangovers after only 1 glass basically. It's my understanding that people with brain injury have more sensitive brains and when we drink alcohol any new connections we built via neuroplasticity immediately disconnect again so all symptoms will be magnified whether the person is aware of it or not. So no, I would not drink. But if you do so safely on your own and don't mind the effects than it's totally a personal choice.
