With both my pregnancies I munched on bananas, milk and dry bread, they were the only foods that didn't make me feel sick, as well as Citrus Fruits. I always felt sick on car journeys too whilst pregnant - try Sea Bands on your writst. With my daughter my sickness stopped at 12 weeks, with my Son it was 16 weeks. It will go, but it is horrible, ironically the first 4 months when you feel quite ill, nobody can see that you are pregnant. Its when you are massive at 8 and 9 months that people offer you seats on buses/trains etc, but I felt really well at the late stages. Good luck
