Having a drink is not usually a problem. Getting drunk definitely is. You are changing the chemical processes in brain that already has struggles. Getting drunk can be as damaging to the brain as a concussion, especially if the brain is in a weakened state.

When I had my third bout with PCS at 16, my neuro wisely told me to never drink. Years later, when I tried to drink, a single tall beer messed me up.

So, you have a choice to make. Do you live a risky lifestyle and suffer the repeat effects of PCS or do you reduce your risk level so you life can be more stable ?

Once concussed, always concussed. That means your system will always be sensitive.

My best to you.
