Cold, flu, food poisoning, morning-after dehydration — the right fluids change by the day. Here's the protocol.

The Sick-Day Hydration Stack

When you're sick, what you drink matters more than usual. Fever increases fluid loss. Vomiting and diarrhea drain electrolytes by the liter. Most "cold and flu" drinks at the grocery store are sugar bombs that make things worse.

Here's the protocol by symptom.

Cold or Flu

  • Hot water + lemon + honey + ginger — basic, but works. The honey is mildly antimicrobial; ginger reduces nausea.
  • Bone broth — sodium and amino acids in a form your gut handles easily.
  • 2THIRTY Day Mode in warm water — sodium replaces what fever is sweating out; B12 helps the foggy-headed feeling.
  • Skip: orange juice. 30g of sugar is bad for an inflamed system, and vitamin C from juice is far less than a single tablet.

Stomach Bug (Vomiting / Diarrhea)

  • Sip — don't gulp. Tablespoons every 5 minutes for the first 2 hours.
  • Pedialyte or DripDrop — these are oral rehydration salts, designed for exactly this. The sugar isn't optional — it drives sodium absorption.
  • Coconut water — softer landing than Pedialyte if you can't tolerate the taste.
  • 2THIRTY is a backup, not the first pick. The sodium dose is right but the lack of glucose means it absorbs slower than an ORS. Use once you can hold down clear fluids.
  • Skip: sports drinks like Gatorade — too much sugar, too little sodium for the diarrhea protocol.

Fever

  • Water + electrolytes, constantly. Fever increases water loss by ~10% per degree above normal.
  • Ice chips if you can't tolerate liquid.
  • Light broth — calories and electrolytes without taxing the stomach.

Morning-After Dehydration

  • 2THIRTY Night Mode immediately on waking. NAC and Milk Thistle support the liver; sodium pulls fluid back into cells.
  • A second stick 2 hours later. Most people don't sip enough on the first round.
  • Eggs + toast + salt. The cysteine in eggs supports glutathione production; the salt and carbs accelerate rehydration.

When to Stop Hydrating Yourself

Call a doctor when:

  • You can't keep fluids down for more than 12 hours
  • Signs of severe dehydration: no urination in 8+ hours, dizziness on standing, confusion
  • Fever above 103°F
  • Symptoms in a young child, elderly person, or anyone immunocompromised

For everything else, the protocol above is what works.

Frequently Asked Questions

Is Gatorade good when you're sick?

It's better than nothing, but it has too much sugar and too little sodium for a real stomach bug. For everyday colds, plain water with a 2THIRTY stick is a cleaner option.

Should I drink coffee when I'm sick?

If you normally drink it and you're tolerating fluids — yes. The caffeine helps the headache and post-nasal grogginess. If you're dehydrated or nauseated, skip it.

Can I drink alcohol when I'm sick?

Don't. Alcohol suppresses immune function, drains electrolytes, and interferes with most cold and flu medications.
