Thanks for the tip. I don't have carbs before bed, as per Berardi/Lowery's suggestions. I will give that grean tea a go - I have thought about having mint tea too as mint is meant to have a settling/soothing effect on the stomach (not sure about appetite suppression though).
Fiber - didn't think of that, as fiber usually goes together with carbs. What I can do, which I have done before, is use some Xanthan gum in the CC to make it far thicker and smoother than normal, and it additionally adds pure fiber.
