I was deathly ill with nausea from time of inception till delivery.
I used ginger and also an anti nausea bracelet. It had a pressure point on the wrist and worked for me.
I'm sorry she's experiencing this.
With my first pregnancy they almost hospitalized me at 6 months because I was losing weight and not gaining. My first was 9 lbs at birth..so I guess I did eventually keep food down. <smile>
My second and third pregnancies were just as bad if not worse on the nausea. I was just as sick except with the third I had gestational diabetes. Oh boy, nausea and no sweets! <smile>
Best of luck to your friend,
