Suzanne, this may be just a phase you are going through with this condition.
I hate to bore you with Ami, but for me it dampened the eye nystagmus enough so I could continue to use the computer for hours on end. Without Ami, I would feel extremely uncomfortable and could not continue to watch.
My condition has yet again morphed so now I can use the computer without any meds. I'm far from recovered though, but something has stabilised (my guess is my inner ear is no longer leaking so much during the day so brain is less upset).
You may have to take a reign check from computers until you can find something to sort this out, or your condition yet again morphs into its next phase when this no longer bothers you
Wishing you well,
