I can't imagine going to college and dealing with PCS. Sorry to hear of your struggles. I know I post similar advice a lot on here, but it's only because I wish someone had told me when I started posting that the 1st thing you need to do is get your vision checked by a neuro optometrist. Someone who can prescribe prism or tinted glasses. Going to regular neuro was a complete waste of time I found.

If it's a vision issue, it doesn't matter how much you rest or what supplements you take. You brain will constantly be overloaded and reading or being on the computer will make you feel symptomatic right away. Best of luck.
