Hi, I wasn't sure if it was because my body was getting ammuned to the mestinon, or if it's because when I use it, I tend to do more, and in turn it make my muscles weaker, and maybe I need more. I'm just not sure. But I can't have too much, and it hates my GI tract. And I mean hate.
I'll have to ask my doctor which one is probably happening.
Love Lizzie
