Barbara,
I have taken dehydration into account. I keep a gallon of water next to my bed. I also drink Powerade some days, and ensure for breakfast every morning. All bloodwork is normal except I am vitamin D deficient.
However, with that being said, I will note that I cannot get as much fluid and nutrients into me as I would like. Eating or drinking small amounts now keeps me painfully full for hours, (either because of the hernia or because of something else).
Also palps on empty stomach only seemed to bother me in the beginning. Now it mostly seems posture related. OAN symptoms also seem worse during PMS, I can barely stand right now when I was able to walk through the grocery store last week.
