I think i've reached a point where i have stopped feeling the constant symptoms of Post Concussion, that is, if i don't happen to hit or even bump my head slightly. However, i've noticed that there are some things that greatly help reducing the aftermath. In the past, a slight bump to the head would leave me dizzy and bogged down for over a day but now i stick to this drill:

Never be hungry or dehydrated
If i'm hungry, i'm weak and more propense to the PC symptoms. Try to find a good balance between proteins,complex carbohydrates and a lot of vegetables.

Stick to the Migraine Diet
Migraineurs follow a diet with no stimulants, dairy foods, chocolate, sweeteners, nuts etc. There are many online resources detailing the diet.

Feeling the PC symptoms coming or got hit? lay down immediatly and have something to eat or drink
Specially something with carbohydrates, potassium and magnesium.

Work on reducing anxiety and stress
These are the worst enhancers of PC symptoms, they can aggraviate them greatly if you let them dominate you.

That's what i've learned so far. It has made my life a lot more bearable, i hope it can help someone out.
