Probably. I do know that when we eat our pancreas shoots out what is called an "Ample" amount of insulin. If mine if shooting out too much when I eat that very well could explain the fatigue. AND the fact that I want sugar during that time, I mean SUGAR!!!! Koolade, candy stuff like that. A little of that and I feel a little better. But since I have changed my eating habits over the past couple months I haven't had that happen very much, maybe a few time as opposed to a few times A DAY before.
