Have you tried Ginger at all.
All three of my pregnancies have been different and i have craved different things at different times to ease the sickness. Curry worked really well first time round but hubby didn't like it on his plate with salad and tunafish??? Ginger biscutes also helped in the early days and cheese, cheese, cheeses...maybe why i put our stone on with that one? LOL
Baked beans were my second babies sickness off put and diet coke and donuts the third.
I go through phases of eating stuff for days or weeks then not being able to stand them! I'm onto drifters at the mo, buy three packs get one free at asda doesn't help LOL
Try cuppa soups too. They are great if you can't eat much but boost your sugar/salt levels and re-hydrate you at the same time
