I Wake Up With A Hungry, Empty Feeling In My

I wake up with a hungry, empty feeling in my stomach and then proceed to gag and dry heave. The gagging and dry heaving can also happen at night, and then I get so cold. Trying to brush my teeth is a fiasco. I manage to get through my work day without gagging/dry heaving, but there are times I need to wrap a blanket around me. This has just started occuring in the last month or so. I just lost my mother and have quite a bit of stress going on in my life so you have a little background.
