I might be delusional, but I don't get as sick as I used to nor as often, and when I do it is just better for me to vomit rather than try and settle the stomach and let whatever toxins my body is trying to get rid of pass through. It seems like my stomach shuts off power to the tract and needs to evulse its contents to better combat whatever bug is running around so I let it do it's thing.

Lots of water, sometimes with an a touch of salt or emergen-c in it to give me something to eject if need be and otehrwise keep me hydrated and away I go.

I'd agree with the suggestion of rice, or also try plain broth or miso soup. I've found that broths help settle my stomach and also satiate when I'm sick (and provide electrolytes and hydration) which has become more effective for me than crackers. You could also put some rice in that if you're feeling a need to get some bulk in while recuperating. An instant soup with rice noodles (check your Thai/Asian section) is still better than a gluten-dependent instant variety, despite being starch laden. There are also gluten free crackers out there, but most are TERRIBLE and just a starch fest. Feel better!

I have found that unfiltered Apple Cider Vinegar does the trick. Just a teaspoon at a time. It tastes awful going down, but really can calm the stomach. This helped me earlier in the year while I had the flu.

If you are trying to calm nausea, but want to eat, you could use rice with butter, rice crackers or chicken soup (any meat based broth would work).

If you are experiencing vomiting or diarrhea, you will also be losing electrolytes along with fluids, so it would be helpful to replace those in warm broths.

The BRAT diet is often used in SAD, but an adaption might be something like this:

B: (bread) rice crackers R: rice A: (applesauce) sweet potato T: tea

Pumpkin! Like canned pumpkin. It will work on sick dogs too.

Maybe slices of baked, then cooled, sweet or white potato?

Peppermint and ginger are known for helping the stomach.

Several years ago I bought lemon grass which is usually kept in water at Asian Grocery stores. It may be already starting to root or you can root it at home. I then planted it in the yard (FL). Lemon grass tea is very good for upset stomachs...it can be mixed with fresh ginger and or chamomile if you like.

People who've recently had a stomach virus said they couldn't keep down anything, not ginger ale, not water...anything they put in their mouths came up immediately. My son was at the end of second day with this flu and he asked that I bring him over some chicken broth and some of the tea. He went back to work the following day. Another more sickly (SAD) friend had it for over 5 days and got very dehydrated.

In a pinch, and if the other stuff doesn't work, white rice would be a better alternative than crackers and would probably work just as well. It's a bland food just as crackers are but it has no wheat and probably is less damaging overall. I consider rice to be basically an empty food but probably not too damaging if consumed only once in a while and if you don't have any blood sugar problems. And for whatever reason, it is very easy on the stomach and digestion for many people.
