you know, my wife had extreme hyperemesis during both of her pregnancies, and throughout the whole thing, not just the first trimester....in fact, she puked bile when she was in labor! but nothing really helped her, not much. the only thing that could kind of help her was to suck on those green striped peppermints, and that only helped a tiny bit. other than that, she tried peppermint tea, ginger, ginger tea, flat coke, sprite, zofran, phenergan.....pretty much everything. towards the last month she finally began to gain weight, and the babies were healthy the whole way through, it just sucked. i hated to see her cry all the time because she hated to throw up. but hopefully you don't go through the same thing.
