What can you eat that doesn't make you sick or give you heartburn?

Please help.  Almost 31 weeks and the all day throwing up has actually gotten worse. I can't figure out what to eat. Please share any foods that you have found don't make you sick. It's to the point where if I don't get my hydration under control I'm going to be in the hospital :(  They gave me reglan (Rx) and diclegis. Diclegis helped a little but I've been on that all pregnancy. Reglan helped for about 2 days. Hope the next 9 weeks fly by.
