It's so weird! I have that too. When I get up it's like everything gets really dark and sometimes i can't see anything!! And it's been getting worse over the years. What is this?
Yes it could be your blood sugar or low blood pressure. Since you have a history of low blood sugar I would suspect that is the culprit. I would see your doctor to get your blood sugar tested and blood pressure. Also, in the meantime try to eat a bit of protein (nuts/ whole grains etc.) more frequently througout the day or have small meals 6 times a day that include protein (plants proteins, whole grain, nuts or meat) it may stabilze your blood sugar. Best to get tested before doing this if you can.
Thanks for the help I will go in and be tested, I will also let you know what the doc says.
