Thanks for the replies.

I'm going to monitor myself closely. I worked outside, and around our house Saturday in pretty hot south Alabama weather. No problems.

My shortness of breath issues last year came when I was exerting myself pretty good in hot weather. I am really careful about how much physical effort I put into anything I do.

I notice that I have some minor ocular (diplopia) issues in the mornings as I work part time in front of a computer. I think I am going to start taking a Mestinon in the mornings and see if there are any differences.

Otherwise, I am feeling better than I have in Months.

I appreciate your responses.

Regards.
