Go for you about the drinking. Research shows that those who have a high level of intellectual function will notice more PCS symptoms. It is much easier to tell when a Ferrari is out of tune compared to a Toyota. The high revs are just not there.

It would be good if you could tune back you intellectual intensity for a while. Your brain will recovery better with less intensity. No energy drinks or caffeine beyond a single serving per day.

Give your brain the break it needs and you will be fine.
