I know when my stomach starts to hurt I get really hot and over whelmed with pain, then I throw up :/

I used to throw up ALOT! Found out I have achalasia-got so severe that they took my esophageal sphincter out and reworked a couple areas of my gut. I only get nausea from extreme pain.....

Do you throw up the same time every day? Maybe you can keep a journal of when you get ill to see if there is a pattern emerging. Would a change of work hours help? Just a few ideas to think about ...
