Just thought I would report that I have had an ECG, potassium levels checked, full blood count and vitamin B12 done. Everything is absolutely normal thankfully. So I am clearly eating the right food. The doctor thinks that although my blood pressure (98/41 or 70/50) is low there are no other indications there is nothing wrong and this measurement is okay for me. Possibly low because I do exercise daily. I don't faint or anything and actually I do feel pretty good. Thank you everyone who gave me advice. I am so glad I don't have adrenal insufficiency as that was a scarey thought for me.
