Try and rest as much as possible
Avoid stimulation, caffeine, tobacco, alcohol, and overstimulating environments.
No heavy lifting or strenuous physical activity.
No TV, txting, or anything like that. Avoid "screen time" as people here call it
A lot of us use audiobooks to pass the time.
It's all kinda depressing I know but its best for healing.
Start taking Omega fatty acids if you are not already.
Be sure to see a Neruologist - they are much better at finding problems than we are. Once you know what the problems are, they can start to tailor a solution
I know how frighting it is, I'm still dealing with it myself on a daily basis. Try and get your husband to read up on PCS so he can be as supportive as possible. Best to have him "in your corner" as Mark would say. I imagine Mark from Idaho will chime in, he's kinda the go to guy on this forum.

I'm a google nut, I google everything and sad to say (no offense guys) that this is pretty much the best resource on the web about Post Concussion Syndrome - It's very frustrating that there isn't much about it from the medical literature perspective. Most things here are anecdotal but really the most realistic - concussions are grossly misunderstood.
Hang in there!
