I've had a weak stomach my entire life and I figured as long as I was home dying of a stomach bug, I might as well offer some tricks I've used and heard of over the years to settle a sour, miserable, crotchety stomach...
1) Ginger (or peppermint)tea - Whether hangover raw stomach or stomach bug, this is often the only thing I can get to settle my stomach.
2) Warm ginger ale - If ginger tea is not your thing, ginger ale will usually do the trick. The bubbles often help, but some people prefer it flat. Either way, don't go cold.
3) Warm Coke - Not diet, for some reason the sugar and the Coke-ness can often help.
4) Ginger snaps - Yeah, I know. I'm sticking with the ginger here. But really, if your stomach is raw and you're miserable, ginger snaps can keep your stomach from eating its own lining.
5) Baking soda - Warning : this tastes terrible, so if you're really, really, trigger-happy nauseous, this may not be a good option. But mixing two teaspoons of baking soda in a glass of warm (not hot) water and taking a few sips can neutralize stomach acid both in your stomach and in your mouth. It can help, but it's not pleasant.
6) Heating pad - This sounds like such an old lady trick, but seriously... apart from helping with my back problems, a heating pad held to your stomach can ease stomach pains and intestinal cramping. It's glorious. Sometimes I fall asleep hugging my heating pad only to wake up feeling 1000% better.
7) PeptoBismal - In my lifetime, I've probably downed gallons of this stuff. It works pretty well, but occasionally, it will not stay down long enough to work.
8) Potato Chips - Wait, wait. I know it sounds crazy. But there's a certain stomach rawness (not hungry, not hungover) that potato chips totally cure. I think it's the salt. My mother has had the same experience. It's awesome.
9) Rub your stummy - I can remember many a night, lying in bed feeling miserable, with my mother rubbing my stomach to try and ease the pain enough to get me to fall asleep. Now, there's just me. I have to massage my own stummy, but that's cool. It often helps.
10) Apple Cider Vinegar - 1 tablespoon of apple cider vinegar, a pinch of salt and a pint of water. This will usually settle nausea and make you able to eat again. Actually, apple cider vinegar is reported to fix *everything*.
11) The fetal position - Never underestimate the power of the fetal position.
12) Plain (slightly burnt) toast - No butter, no peanut butter... a smear of jam and crunchy, slightly burnt toast. I think I've had one hangover where I couldn't keep this down. The biggest problem is finding the will to swallow.
13) Charcoal tablets - I discovered these in Russia and, at first, absolutely refused to try them. However, once I did, it was like a miracle. Those things are fabulous. They probably destroy something in your body, but my god, they work to settle a stomach... and intestines.
14) Yoghurt - If you can stomach dairy, yoghurt with active cultures is genius for stomach issues.
15) Clear soups - Chicken soup, vegetable broth... something that won't require too much processing
16) Marijuana - While it's not my remedy of choice, it is recommended for cancer patients to help them eat during chemotherapy. If it can work for them, it should work for your tummy-ache.
17) Spruce tea - Seriously, tea made from spruce tree needles (make sure they're absolutely green).
