Taking them at night worked for me. By the time I digested them I was alseep and didn't have a problem. But is the taste making you gag? I tried one pre-natal that had a nasty taste that wouldn't go away no matter how much I drank, if they taste bad change brands. I use Materna and love them. (but the generic version of Materna I can't take because of the taste) There are also new prenatals that have a 2 dose per day dose...these are easier on your stomach because it breaks up the doses of all the vitamins into 2 so your body doesn't react to the big overload of the one a day kinds. Ask your OB. Goodluck.
