Aw poor you. I was awful with Ella - barely ate for 9 months at all. Was the same with twins, but ths time iwas forced to go on anti sickness tablets. And they didn't help that much.
Only thing slightly helped me was spearmint softmints.
Have you tried lillipops ( think that right name). Google morning sickness lollipops. They supposed to help - they made me even sicker but maybe worth a try?
Tbh none of the remedies ever helped me throughout either pregnancy
i was sick up until all 3 were born - kinda why I was forced to have section with twins as was so sick just before they checked me, and discovered by me being sick I knocked the clip off Katie's head and she then turned her head almost as if looking up at me to check I was ok so became in a very dangerous position.
Hope you get some relief soon
