Thanks for your post. I don't know if any of our regulars have MPFS or not - altho I would guess not as I might recall it. I do know a number of us have had fasciculations, but as a more limited subset of PN. I used to occasionally experience them (I still do get strong and painful cramps, but as you said - those are not related to MPFS) - - but since I started taking magnesium (and calcium) they have essentially disappeared.

I am guessing that you may either be taking magnesium, or have tried it. I wonder if it made any difference in your situation. We have a very active and excellent board here . . . lots of great folks with quite a varied background. A number of us have scientific backgrounds (or are self-taught) of one sort or another. And some of us are even likable
