D.G.
I was always so sick that i had to stop taking them. the 2nd one I even tried taking them at night. and then I switched to the chewable ones. but still no good. so for most of my pregnancies I didn't take them. My dr finally told me I was better off not taking them if it meant I could eat some and try to keep something down. and I had enough other problems to worry about that and those were the reasons my babies were born early but healthy even without the vitamins!
