I Have A Mild To Medium TBI That Has Mee

I have a mild to medium TBI that has mee disabled. I am currently on Ridalin due to permanent cognative damage. It is not working well anymore and my Dr told me to reseach the other meds. I'm thinking Addiral would be my next be option. Is there any reason you would recomment Nuvigil or Provigic?
Or any other medication? Thanks Sue
