HELP! What foods have helped with your morning sickness and heartburn??

Lauren
I'm 8wks along with major heartburn and morning sickness. No vomiting, but consistently nauseous ALL day and night. No matter what I eat, I get heartburn.. I've tried eating light, plain foods, I've tried non-acidic fruits, potatoes.. Nothing works/helps.
Anyone have anything that's worked particularly well for them??
