I ate a big meal last night and from 1am to now (7am) I have been having this pain in my chest. Any help?

Chest Pain for 6 hr. This could be very serious. Chest pain can occur with heart attacks, pulmonary problems, gastric regurgitation of stomach acid, gall bladder attack, gallstones and many other disorders. You should call 911 if you are still in trouble or get to the er.
See your doctor. If you have chest pain that long you should go to the er asap. See some of the causes in the cartoon.
