Sometimes I can tell I really must go but simply can't. Other times I have the gas to go but simply don't understand the process and end up a small elimination. This means that when my body says move all this out and I only move a portion, I have to compensate by adjusting my diet. Well, this lousy bm or lack of any bm means my diet is quite skimpy and though I don't experience long lasting hunger I do not adjust well to having 1 meal a day.
