Blackout Wednesday is the nickname for the night before Thanksgiving. In 2026 it falls on Wednesday, November 25, with Thanksgiving on Thursday, November 26. College students and old friends are back home, almost nobody works the next day, and hometown bars fill up. In Boston that means packed nights in South Boston, the Seaport, Fenway and Allston.
This guide covers what the night is, how to plan it safely, what the science actually says about hangovers, and what you can do if you wake up Thanksgiving morning with a family dinner to get through.
What is Blackout Wednesday?
Blackout Wednesday (also called "Drinksgiving" or "Thanksgiving Eve") refers to heavy drinking on the night before Thanksgiving in the United States. It is often described as one of the biggest bar nights of the year. It also has a darker side: in some places it is one of the worst nights of the year for drunk driving, and many police departments add patrols that night.
When is Blackout Wednesday 2026? Wednesday, November 25, 2026.
Why that night? It is a homecoming night. People are off work Thursday, and friends from high school and college are back in town.
Is it a real thing? Yes. It is not an official holiday, but bars, police and safety groups all plan around it.
Plan your ride home first
The single most important plan for the night is how you get home. Decide before you go out:
Pick a sober driver or agree on a rideshare before the first drink.
Use the T where it works for you. Check the MBTA for last trains on your line, since late-night service ends earlier than many people expect.
Charge your phone and share your location with a friend.
Never let a friend drive after drinking.
Know the signs of alcohol poisoning
Call 911 right away if someone has any of these signs, and don't leave them alone:
Confusion, or they can't be woken up
Vomiting while not fully awake
Seizures
Slow or irregular breathing
Pale or bluish skin, or a low body temperature
This is a medical emergency. Letting someone "sleep it off" can be dangerous. An IV hydration clinic is never the right place for alcohol poisoning; the emergency room is.
The honest truth about hangovers
According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), there is no cure for a hangover other than time. Your body has to clear alcohol's byproducts, rest, and recover. Coffee, a cold shower or "hair of the dog" won't fix it.
Alcohol does cause mild dehydration. It blocks a hormone that helps your kidneys hold on to water, so you urinate more. That fluid loss likely adds to thirst, tiredness and headache. Poor sleep, an upset stomach and low blood sugar pile on too.
The NIAAA also notes that research has not shown that extra electrolytes, including IV treatments, make hangovers less severe. We think you should know that before you book anything, including with us.
Before you go out: simple things that help
Eat a real dinner with protein, carbs and some salt.
Alternate drinks with water. One glass of water between each drink slows you down.
Set a limit and tell a friend what it is.
Put water and a snack by your bed before you leave.
Thanksgiving morning: getting through the day
Drink water slowly, plus something with electrolytes if your stomach can handle it.
Be careful with pain relievers. Acetaminophen (Tylenol) and alcohol can be hard on the liver together. Ask a pharmacist if you aren't sure what's safe for you.
Rest. A nap before dinner does more than another coffee.
Where an IV fits in
An IV won't undo a big night, and most people recover on their own. Some people still choose an IV because they can't keep water down, have a long drive or flight home, or host dinner and need to be on their feet. What an IV can do is give you a liter of fluid in under an hour without relying on an upset stomach.
Every IV at IV League Hydration starts with 1 liter of Lactated Ringer's, a balanced fluid with sodium, potassium, calcium and lactate. A licensed nurse reviews your health history and medications before every drip, and will turn you away if a clinic visit isn't safe for you.
The Hail Mary, $189: the Gamechanger plus Zofran (an anti-nausea medicine) and Toradol (an anti-inflammatory pain medicine). These are prescription medicines, and the nurse will check whether they're right for you. Toradol isn't safe for everyone, for example people with kidney problems, stomach ulcers or bleeding risks.
Most drips take 45 to 60 minutes. See every option on our hangover IV page.

Wednesday, November 25, 2026, the night before Thanksgiving (Thursday, November 26).
Why is it called Blackout Wednesday?
The name refers to the heavy drinking many people do that night, since most people are off work Thanksgiving Day and friends are back home. Blacking out is a sign of drinking a dangerous amount, not a goal.
Does an IV cure a hangover?
No. Nothing cures a hangover except time. An IV can rehydrate you quickly, and the Hail Mary adds anti-nausea and pain medicine when a nurse decides they are appropriate, but research has not shown that IVs make hangovers less severe.
How much is a hangover IV in Boston?
At IV League Hydration in South Boston, drips start at $79 for the Rookie + B12 Special. The Gamechanger is $159 and the Hail Mary is $189. House calls add a $100 concierge fee per person.
When should I go to the ER instead?
Go to the ER or call 911 for confusion, someone who can't be woken, vomiting while not fully awake, seizures, slow or irregular breathing, chest pain, or vomiting that won't stop. A wellness IV is not emergency care.
