Thanks so much Jan. As usual you provide a wealth of knowledge. I look forward to reading the article, but my new computer won't let me access it for some reason at the moment.

I tried mexiletine 150mg on Sat with no problem, but when I took a second dose on Sunday morning with my thyroid medication my HR became very elevated for several hours. Nothing seems to be very easy...

I see you have added the SCN4A mutation to your "type of "myotonia". I have done so as well. I find myself wondering if that combo might have some added medical impact...

Type of Myotonia: Thomsens + SCN4A mutation
