I also feel weak in the mornings, low blood sugar to blame. I eat oatmeal (acacia sprinkled on) with some berries, and drink water with acacia. This settles my stomach pretty well and then I have something more substantial like peanut butter on toast, soy milk, or egg whites. I eat often in the morning, little snacks of safe food. I also have a Luna bar if I'm feeling like I need more energy to keep me going until lunch. I eat an early lunch and make sure to get lots of protein. Have you tried Luna bars?
