I drank a lot of iced lemon water. It really helps. Also pickles.
I swear by Zantac for all tummy problems. I even have a prescription to take double the max dose every day. (I have an invisible stomach issue that behaves like an ulcer and gives me pains that feel like contractions).
I take it twice a day (hence it totals twice the max strength) and my stomach feels great as long as I stick to it. Over the counter comes in various strengths and the maximum strength even has an option that includes mint to give a cooling sensation.
If you're not much for medicine, I recommend trying ice cream. Not a whole truck load of it or anything, like half a pint at a time. I personally prefer chocolate chip when my stomach is upset, it's not too much flavor but it's still yummy.
Ginger chews are great if smells heighten it. I stick one in my mouth if there is a smell bothering me. Its a life saver, just keep a pack always in my purse!
Peppermint or ginger tea work great
Take alca selizer it soothes stomach feel better
