Seems to me if you are having nausea in the morning you might have slipped down off your wedge pillow or too low on it to prevent esophagus reflux. This happened to me. The other problem I had was that I was continuing to suffer from slow stomach emptying so last night’s food was still in my stomach not digested so that gave me nausea in the morning. I tried raising the head of my bed by putting books under it and that helped a lot, as well as a change in prescriptions. I now take domperidone (the biggest help) as well as Previcid and sucrafat.
