Thanks for this information, and I am sorry to read what has happened to you - I wish you well. Your right about the need for supplements, I read somewhere that magnesium may help with light sensitivity so I am taking this along with omega 3. I do think I will recover, the key isn to do the things that you can and avoid the things that provoke PCS symptoms. Overall it has been the biggest battle of my life, but one I will hopefully win.
