I like Brisk Ice Tea on the way down but even more so on the way up! We had a whole conversation on this a few weeks ago on the first trimester forum...
Worst ever puke so far: cream of wheat. Thought it'd be easy on the way up due to the texture, but I didn't factor in how much it would sour. Ugh. Splashback was bad too. Never again.
Chili came in at a close second. My mother made some for herself and I ventured a few tastes... BURNED on the way up. *shudder*
Ramen noodles are OK up and down, although considerable splashes and it's a bit sour on the way up. Easy to wash taste out of mouth though.
Strawberries are not too bad on the way up, they don't taste as good but they're not terribly nasty either and less of a burn than with some other fruits.
Chocolate cake turns SOUR coming up, nothing I'd recommend, sour chocolate? Whoever heard of it... Plain chocolate, ironically, tasted the same up and down. Weird.
Believe it or not after all this time I'm starting to be OK with bile, even the taste doesn't get to me. I even prefer the empty stomach pukes to food coming up. Less splash and less of that nasty throat irritation of too much food coming up at once. (I never had this problem pre-HG... for some reason my stomach now wants ALL the food out at once, doesn't stop to consider my throat's width has its limitations.)
