I can get fatigued in the morning from reading, etc. but once I have a nap, I can do just about anything the rest of the day. I know I have reactive hypoglycemia and wonder if it could be the cause. A drop in blood glucose can cause fatigue.

I used to check my glucose level and it could drop to 60 or below. Normal should be 80 to 90. A glucometer can be purchased for $60 to $80 plus test strips and lances. Some journaling of food intake and blood sugar levels can help to figure if it is related to blood sugar.

When I told a doctor I was doing this, at first he thought I was a hypochondriac. Then, I told him I was trying to see if it was related to fatigue and sleepiness and he agreed it made sense.

btw, Reactive hypoglycemia is a roller coaster of blood glucose after eating intense carbs with swings from 120 high to as low as 60 or even 40. 40 can be almost comatose.

I would bet on the fatigue... I've been super girl all my life...the fatigue is unbelievable debilitating.
