I have had very similar issues. The dietitian I meet with suggested that I try eating something immediately after waking up even if I'm not hungry at all......even if its just a piece of toast. She said this could help and it honestly has. Hope it helps you too.
It may sound gross, but an old German lady told me years ago to try this when nauseous, or just for a snack. Toast am English muffin, lightly butter it, spread cottage cheese on it, then drizzle a little orange marmalade. You get your carbs, protein, and a little sweetness. It worked for all of my pregnancies when nothing else would.
That actually doesnt soubd too bad :)
