After throwing up, your body needs a short recovery window before you start feeling like yourself again. The exhaustion, shakiness, and lingering nausea are all normal responses. What you do in the next few hours matters: the right steps can cut your recovery time significantly, while common mistakes (like gulping water or brushing your teeth right away) can make things worse.
Why You Feel So Awful Afterward
Vomiting is one of the most physically intense things your body does. It engages your diaphragm, abdominal muscles, and throat all at once, which is why your core and ribs can ache afterward. But the exhaustion goes deeper than sore muscles.
Your vagus nerve, which runs from your brain to your gut, goes into overdrive during vomiting. This triggers what’s called a vasovagal response: your blood pressure drops, your heart rate shifts, and you can feel dizzy, faint, clammy, or completely drained. That washed-out, shaky feeling isn’t in your head. It’s your nervous system recalibrating. Give yourself permission to lie down and rest. It passes, usually within 15 to 30 minutes.
Rinse Your Mouth, but Don’t Brush Yet
Your first instinct will be to brush your teeth. Don’t, at least not right away. Stomach acid coats your enamel during vomiting, and brushing while that acid is still on your teeth grinds it into the surface, causing erosion. Wait at least 30 minutes before brushing.
Instead, rinse your mouth with plain water right after vomiting. This washes away acid and food particles and gets rid of the taste. If you have baking soda on hand, dissolving a small amount in water makes the rinse even more effective at neutralizing the acid. Spit it out, don’t swallow.
How to Start Drinking Fluids Again
Dehydration is the biggest risk after vomiting, but flooding your stomach with liquid too fast will likely trigger another round. The key is slow, deliberate sips. A good target: about two large sips (roughly 30 mL, or one ounce) every three to five minutes. If that stays down, you can gradually increase. If you vomit again, slow down your pace even further.
Start with plain water or an oral rehydration solution. Sports drinks work too, though they contain about three times less sodium than medical-grade rehydration solutions. In practice, the volume you drink matters more than the exact formula, so choose whichever liquid you can actually tolerate. Flat ginger ale, diluted juice, and broth are all fine options. Avoid anything carbonated, very cold, or very sugary until your stomach has settled, as these can irritate an already sensitive lining.
If you haven’t urinated in several hours, your skin doesn’t flatten back quickly after you pinch it, or you feel increasingly dizzy and confused, those are signs of dehydration that may need medical attention beyond what sipping fluids at home can fix.
Find a Comfortable Position
How you position your body makes a real difference. If you’re lying down, try your left side. Research on acid reflux shows that lying on your left side helps stomach acid clear from the esophagus much faster than lying on your back or right side. This can reduce that burning sensation in your throat and chest that often lingers after vomiting.
If you’d rather sit up, propping yourself at an angle (a recliner or a wedge of pillows behind your back) keeps gravity working in your favor and reduces the chance of acid creeping back up. Avoid lying completely flat, especially if you’re still feeling nauseous.
Managing Lingering Nausea
Sometimes the vomiting stops but the nausea hangs on. Ginger is one of the best-studied natural remedies for this. Clinical trials have found that about 1 gram of ginger per day, taken over several days, significantly reduces the frequency of vomiting. You don’t need a supplement to get there: ginger tea, ginger chews, or even a thumb-sized piece of fresh ginger steeped in hot water can help settle your stomach in the short term.
Peppermint tea or simply smelling peppermint oil can also ease nausea for some people. Cool, fresh air helps too. If you’re stuck in a warm, stuffy room, cracking a window or pointing a fan toward your face can reduce that queasy, overheated feeling.
For over-the-counter relief, pharmacies carry phosphorated carbohydrate solutions (sold under brand names like Emetrol) designed to calm stomach contractions. The standard adult dose is one to two tablespoons, repeated every 15 minutes as needed, for up to five doses. These work best for mild, lingering nausea rather than active vomiting.
When and What to Eat
You’ve probably heard of the BRAT diet: bananas, rice, applesauce, and toast. It’s a reasonable starting point for the first day or two, but there’s no clinical evidence that restricting yourself to just those four foods speeds recovery. Harvard Health notes that brothy soups, oatmeal, boiled potatoes, crackers, and plain dry cereal are equally easy on the stomach.
The goal is bland, low-fat, low-fiber foods in small amounts. Don’t force yourself to eat if the thought of food still makes you queasy. Your body can handle a few hours without a meal. When you do feel ready, start small: a few crackers, a few spoonfuls of broth, half a banana.
Once your stomach has settled (typically after 24 to 48 hours), start adding more nutritious foods back in. Cooked carrots, sweet potatoes without the skin, avocado, skinless chicken or turkey, fish, and eggs are all good next steps. These are still gentle on digestion but provide the protein and nutrients your body needs to actually recover, not just coast.
What to Avoid in the First 24 Hours
- Dairy products: Milk, cheese, and yogurt are harder to digest when your gut is irritated and can worsen nausea for many people.
- Fatty or fried foods: These slow stomach emptying, which prolongs that heavy, nauseous feeling.
- Caffeine and alcohol: Both are dehydrating and can irritate your stomach lining.
- Large meals: Even if you feel hungry, eating a full plate too soon is a common trigger for a second round of vomiting. Eat small amounts frequently instead.
- Strong smells: Cooking odors, perfume, and cleaning products can retrigger nausea when your system is already on edge. Keep your environment as neutral-smelling as possible.
Signs That Something More Serious Is Happening
Most vomiting from food poisoning, stomach bugs, or overindulgence resolves on its own within 12 to 48 hours. But certain patterns signal a problem that home care won’t fix. Seek medical help if you notice blood or what looks like coffee grounds in your vomit, if you can’t keep any fluids down for more than 12 hours, if you develop a high fever alongside vomiting, or if you experience severe abdominal pain that doesn’t let up between episodes.
In children and older adults, dehydration can escalate quickly. Watch for no urination for three or more hours in infants, a rapid heart rate, skin that stays “tented” after being gently pinched, or unusual drowsiness. These are signs the body is losing fluid faster than sipping can replace it.
