Thats the first time I've ever had the abdominal cramps, but the Mestinon was the only thing I could relate it too, so it was worth a try.
When I first started taking Mestinon I was taking 30 mg 3x a day and then as things got worse we upped it to 60 mg 3x a day, but since my Thymectomy in may I have been starting to feel pretty good.
I was going to start by cutting back my IVIG from 3 days every 28 days to just 1 day a month and see how I felt, but I guess we will start by cutting back the Mestinon, maybe this is the first signs of remmission for me

I can only hope and pray that it is
