Jason,

Glad to hear you are ready for a life change for the better.

I suggest you try some nutritional supplementation. Start with a daily regimen of:
Vit B-12 1000 mcgs
a B-50 complex
Vit E
a high potency multi-vitamin like GNC Mega Men (Centrum and One a Day are too weak)
Omega 3, 6, and 9 fish oil
Magnesium (sometimes is combined in a calcium tablet)
Calcium
Good meat protein for amino acids, pork is best but all are good.

It is not uncommon for people to be B-12 deficient. It is needed for nerve recovery.

This helps the brain flush the toxins left by the injury. It takes a month or two to start to see improvement.

Quiet rest is the gold standard for allowing the brain to heal. Nutrition just helps the brain with this process.

Reduce and/or eliminate stress in the form of work stress/deadlines, emotional stress, visual and auditory stimulation, physical exertion, etc.

No alcohol, drugs, caffeine, MSG, and artificial sweeteners. Avoid high fructose corn syrup. Real sugar is better but in moderation.

This is a start. If you have specific symptoms, we can address them, too.

My best to you
