Beth,
Thanks for the support. I really appreciate it.
Dad got new glasses and they have not helped to alleviate his blurred vision. Also I noticed yesterday that his speech was much much worse in the evening than in the morning. Both of these things have me thinking it might be reasonable to hope for an MG diagnosis. Then again, I can easily find examples of PALS on these forums who have experienced these things.
It's easy to drive yourself crazy overanalyzing the symptoms, isn't it?
