Sounds like you need to get started on nutritional improvements so your brain can continue to heal.

There are plenty of discussions about nutritional supplements. The basics are B-12 (500 to 1000 mcgs) Omega 3's, a B-50 or B-100 complex, a multi vitamin with good potency such as GNC Mega Men or an equivalent, calcium and magnesium.

No caffeine or alcohol, artificial sweeteners, artificial preservatives, MSG, or excessive High fructose Corn Sweetener.

A single serving per day of caffeine and/or alcohol can be OK if you don't notice symptoms from it.

Get good rest and sleep and avoid stressors and excessive visual and auditory stimulation.

Hope you start getting back to good function.

My best to you.
