image i thought i was going crazy this morning... the exact same thing happened to me! except i ate a big late lunch yesterday so i never ate dinner so to speak... and then this morning when i was leaving for work i took the women's one a day vitamin for the first time and within 20 or 30 minutes a wave of nausea started coming over me soooo bad. luckily i was able to eat some poptarts to hold it off and didn't end up getting sick.
