This was an fluctuating day. Started off horrible with so much fatigue and lightheadedness, I checked my blood pressure by noon and found it was 98/56 which is a bit too low really. I checked it a few more times through the day and it seemed to jump around a lot. I worry I might have found the "real" problem with me now. Felt better later in the day then went back to feeling just plain bad again at night.
