Salt is definitely the key for me. I usually have a major sweet tooth, but I can't tolerate anything sweet right now. Even ginger ale makes me feel sick. Today I've managed to choke down ants-on-a-log minus the actual ants (and with added salt) and french fries from the cafeteria at work, with fry sauce. Last night it was ramen soup. It feels so strange to have girl scout cookies in my freezer and holiday candy in my cabinet, and not be the least bit interested in eating any of it.
I'd love more suggestions on hydration. I can't take ginger ale, I'm guessing ginger beer would get the same reaction, plain water is the worst, and water with lemon is no better. I'm thinking of stocking up on chicken broth, and drinking that instead of water.
