Morning sickness

For the past two weeks ive been beyond sick! Im ten weeks pregnant with baby # 4 and ive never felt like this with any other pregnancy. If im not puking then i atleast feel like im about to. My stomach burns so bad! If i get too hot i puke, if i smell anything with a strong scent i puke, if i eat i need to puke! I constantly feel like im hungover. Anybody with any suggestions on how to cope till i get out of this phase?
