Hello, @raye. It's about 1 year later -- Hope you are well.

Flomax? Is that the nasal decongestant? I'll look that up. i have been using it the week of diplopia.

I also began having double toward the end of my day which is actually @6 am. I'm a chronic insomniac, though if I take enough drugs I can sleep all day long. After which I can barely walk. My balance is bad to begin with, I have Multiple Sclerosis and bad balance is one of my major problem.

Steroids, yes, can help, but too many oral steroids is bad for your vision. A friend with MS almost lost his vision completely because a new doctor was feeding him oral steroids. IV Methyl prednisone is better, once a week (not entirely sure about that) for a few weeks...

I only have double vision when I take off my glasses to write and read. I'm seriously myopic. Now that they've invented thin lenses my glasses look normal but when I was growing up they were brick-thick. Thinned lenses, sunglass-shaded, don't know how prism lenses could be added to all that...will look that up too.
