I'd double the Fish oil to 2000 mg (Dr. Weil says up to 3000 mg is good) and add Turmeric. Both have been shown to help brain health and promote healing.

As for combating brain fog, nootropics have helped me. They're known to enhance brain function temporarily. People take them before taking tests etc.. I take 1-2 750mg Aniracetam 2X daily (depending on severity of brain fog that day) + 300 Choline daily (It complements the Aniracetam).

I hope that helps. Report back with your findings.
