I Wake Up In Morning Not Able To Eat Right

I wake up in morning not able to eat right away. If I drink something it makes me almost throw up! It gets better as morning goes on. At about 10:30am I start getting an upset stomach and at times feel like throwing up! Happens more during work week then on the weekends. I do not have any tender areas in my stomach. It just seems to feel like bloating but I do not have much gas.
What could this be??
