I couldn't take the vitamins from the Dr or the health department, they also made me sick. So the Dr told me just to get the Flintstones vitamins for kids or the prenatal vitamins from Walmart or somewhere.
I found that just getting something into my stomach first was the answer. So I kept a small plate of soda crackers next to my bed. In the morning, before I even got out of bed, I would nibble on a few. And I would nibble almost constantly. Being hungry and having an empty stomach just made the nausea worse. Hope you feel better soon.
I take my prenatal s at night and I also switched to two flinstone vitamins a night which is the equivalent of a prenatal. It's a lot easier in the tummy. Make sure you always have a little something on your stomach. Before you even get out of bed eat some crackers
