Have you tried keeping a food journal? Just wondering if something keeps coming up that you may not realize.
And you're definitely drink water, as in TONS of it? I know I swing C sometimes, which can be painful, if I don't drink enough water. Feels like a sore muscle in my lower tummy or something. I hate that!
If worse comes to worse, you can always try Kree's Lower Fat Oatmeal Molasses Cookies. I haven't tried them, but apparently they've gotten good reviews for "cleaning you out"! LOL
