So much nausea

I'm about six weeks into my second pregnancy. I remember nausea the first time around, but reliving it is worse than the memory. Thankfully it's not so bad that I've had to vomit—it just makes eating much more difficult. I'm only eating foods that sound good (the list is shrinking by the day.) What are you ladies doing to help you get through your day and choke down your meals? Have you found relief that really works?
