Struggle with low bp. when i wake up in the morning i am extremely lightheaded (no spinning) and its hard to sit up. walking around seems to help i think because it pushes blood in my head. get the same thing if i lay down for more than 15 minutes?

You don't mention your blood pressure readings during symptoms. Can you check them? Extremely low BP would cause worsening of lightheadedness in the standing position usually with improvement when supine. Although you're not experiencing vertigo, inner ear disturbance is still a possibility as is anemia. I recommend being examined by your MD who will check for the possible causes of your AM sympto
