I agree with u/areopagitic on this one as the lack of carbs actually caught my eye as well. I don't know how rare or common it is to be especially sensitive to carbs like my body is but your diet that particular day would not be enough carbs for me and would more than likely flared me as a result. I can't tolerate caffeine unfortunately (due to IC and tachycardia) but it struck me as a possible reason you felt so full and weren't hungry even though your body actually might have needed some more carbs in it to balance everything out. The reason I bring this up is because this happened to be a lot pre-IC when the only drink I consumed outside of water were 2-4 Red Bulls every day. And even before my IC symptoms took off it would cause my bladder to act up.
