I like ginger ale for nausea, also. It won't help if you're dealing with indigestion like gas or heartburn, though. The soda is too acidic and carbonation can help relieve gas if it makes you burp, but it can make it worse, too.
My husband has IBS and if he is nauseous or he has a sour stomach, peppermint tea has been really helpful. If you're bloated, it could be due to constipation and prunes/prune juice can give you some relief. If you're just bloated from retaining water, drinking extra water is a good idea.
And remember that you should try to treat the cause, not just the symptoms. It's always good to get some relief, though.
