Got to feeling all lightheaded with "blown out over-bright" vision again after eating, so once again, tested my blood sugar and blood pressure, as per doctor instructions. This time, blood sugar was 177 mg/dl, blood pressure was 143/112, pulse 119. Wrote down the measurements. Have an appointment with him next Monday.

Testing my blood sugar levels was pretty much "within range" since I was prescribed the meter... until this afternoon, when it read 264 mg/dl . Highest it's been since I began testing. Might have been because I tested right after eating though.

EDIT: Realized later I forgot to take a Metformin tablet after eating my first meal of the day.
