Thanks for your reply. In answer to your question, if I keep my environment controlled, and only read and/or use computer in 40 minute increments, I seem to be ok. As soon as I try to get out in the world, or start to multi-task at home, I begin to feel bad. Sound is particularly difficult.

I currently take a strong B complex and Magnesium Oxide specifically for my concussion. I just started sleep apnea treatment which isn't as bad as I thought it was going to be.
