My blood pressure when sitting is runs between 118/80 to 130/90 depending on stress levels. At night when lying down it is dropping to 109/60 if on my right side and 99/46 if i am lying on my left side. I was a little dizzy last which has never happened before. I do have mild sleep apnea when on back, but I do not lose O2 saturation so I do not have a Cpap. I have significantly over weight, but cardio stress test are fine. I also know that home electronic blood pressure monitors are not that accurate. Any suggestion.
