I don't know if there's much you can do about that. Sometimes, I wake up with a growling stomach, sometimes I wake up with no appetite at all. I'm sure it's normal - after all, we "fast" overnight. I think the only thing you could try is eating a light snack at night, and/or taking the am med with lots of water.

Is it a new medication? Is it possible that it's making you feel a bit crappy? Some meds can do that.
