Wow! Thanks for all your replies. It seems that for most of you, the prednisone (or a combination of prednisone/mestinon) was needed to alleviate the double vision. That is basically what I've been told by the ophthalmologist and the neurologist.

I've had double vision for 7+ years, but just recently had a tensilon test that was positive. All the other tests have been negative, but neurologist feels it's most likely ocular MG. The double vision is now present at all times, sometimes controlled by prisms in my glasses, but gets a little crazy when I'm too active and/or later in the day. At the present time, that's my most concerning symptom. I occasionally have some mild swallowing issues, but it's never been a major problem.

So...part of me feels that my disease is very minor (thankfully), although annoying, and I worry about trading the minor symptoms for some potentially problematic side effects of the prednisone. Can anyone speak to how the side effects of prednisone affecting you?
