morning/ night sickness help!

So I'm 6 weeks today & lately I have been getting sick only at night and throwing up my dinner. Food does not gross me out or anything but no matter what I do it seems to hit me at a certain point every night. It's getting hard to even want to eat when I know I'll just throw it up later. Does anyone have any remedies or things that helped them to keep food down when having morning/ night sickness?
