Thanks! This is a great suggestion. I've been journaling in narrative format for years, just to get it off my chest, but I've set up a spreadsheet now where I track everything. Particularly since I went to Mayo. I want to have something that shows in a less subjective way what I am experiencing.

No one's ever mentioned it to me - we all thought these were just aborted syncopal episodes associated with my NCS and POTS. It wasn't until Mayo when tests seemed to indicate that they might not be that I started trying to work with drs to figure it out more. However, I've run across PP on the internet and subscribe to a list serve. It's another area where a lot fits, but a lot doesn't. I've never tested high or low for potassium and I am on a high salt diet for the POTS and that doesn't seem to make me worse. (Doesn't make me better either, but for PP, I would expect it to make me worse.) Testing for PP is tough too, so I'm trying to rule out the easier things first.

I call it a "controlled collapse." I wondered how it fits with MG. Is there normally warning for you before you have these spells?

Thanks again for your input!
