Thank you, I am unsure if I was dehydrated or is it because of the barley juice that I drank. I am stopping that supplement since my feeling bad are usually on days I am taking that (I stopped that for 1 week and the symptoms, lightheadedness, diarrhea, fatigue went away). Although I checked all the write-ups and articles I can find on the internet and it was not supposed do to that. My blood pressure now is 125/80 and 96 BPM. My bpm is usually high but it goes to an average of 82 while resting.. It goes to 110 when I walk or exercise but when I seat down it falls down so I am not worried... Also, I think I am having some vision problems or at 47, my eyes and brains are becoming confused as my astigmatism might be worsening at this age.. Thank you for the reply
