Last year I passed my physical with flying colors. So much so that the insurance company gave me the lowest life insurance rates they have. Im 31 (male), 5 foot 11, 175 pounds, former military, eat moderately well, excercise, yet I have a problem that has gotten huge. Without Sugar Digest suppliments, my body goes crazy when I eat most foods, especially breads or sugar food. My energy bottoms out, and I get incredibly sleepy beyond normal. I get migrains, and it is frequent. With the suppliment, Im great, lots of energy. Is this pre-diabetes? Why havent my physicals caught anything?
