Hi Alan,
My main problems with the MG until recently have been my eyes. I had double vision continuously for about 8 months., and then I learnt I had MG, one of the biggest helps to me with the double vision is to either close one eye or patch one eye it doesn't make a difference which eye., but this will get rid of the double vision. Also I get the heaviness in the lid and as others said the ice or very cold helps that. I also get the general weakness., especially lately with the heat. I have been diagnosed with MG, and have been waiting to get into a MG specialist the end of August., so my GP has been taken care of any major issues., which fortunately have been none. I just know to close my eyes and rest them when I can., and when I become very tired I rest also. I know some say that the prednisone helped with the eyes., the prednisone's side effects for me were worse than the symptoms, so I do not take prednisone., and the mestinon I had a bad reaction too. Take care
Nancy
