You’re standing in the grocery store aisle, staring at a box of cereal, and suddenly the room tilts. Your head feels heavy, your vision gets a little blurry, and you feel genuinely loopy. But you haven't touched a drop of alcohol in weeks. It’s a bizarre, unsettling sensation. Most people describe it as being "brain fogged," but for others, it’s much more intense—a literal feeling of being drunk without drinking.
It’s not just in your head. Well, technically it is, but it’s not "imaginary."

When you feel intoxicated despite being sober, your body is sending a massive flare-up signal that something in your internal chemistry or sensory processing is off-kilter. This isn't just about being tired. We're talking about ataxia, dizziness, and that "spaced out" feeling that makes you wonder if someone spiked your water.
Why Do You Feel Drunk When You're Sober?
The most common culprit is actually something called Vestibular Neuritis or other inner ear issues. Your inner ear is basically the gyroscope for your brain. If it sends faulty data, your brain gets confused. It feels like you’re on a boat. You stumble. You can't focus. It's an inner ear "glitch" that mimics a Saturday night at the bar.
Then there’s the blood sugar rollercoaster.
Hypoglycemia is a classic imitator of intoxication. When your glucose drops below a certain threshold—usually around 70 mg/dL—your brain literally starves for fuel. Since the brain is the biggest consumer of energy in your body, it starts shutting down non-essential "high-level" functions. You get confused. You slur your words. You might even get irritable or aggressive, which is why police officers are trained to check for medical ID bracelets before assuming a driver is drunk.
The Strange Reality of Auto-Brewery Syndrome
This sounds like a plot from a medical drama, but it’s a real, documented condition. Gut Fermentation Syndrome, or Auto-Brewery Syndrome (ABS), is a rare state where your digestive system turns into a literal distillery.
Basically, an overgrowth of yeast—usually Saccharomyces cerevisiae or Candida—settles in the gut. When you eat carbohydrates or sugar, these fungi ferment the food into ethanol. You aren't drinking alcohol; you are manufacturing it.
Dr. Richard Kaner and other researchers have documented cases where patients had blood alcohol levels (BAC) of 0.25%—three times the legal limit—just by eating a bagel. These people aren't just "feeling" drunk; they are biologically intoxicated. However, because the alcohol is produced in the small intestine, the "hangover" and the rise in BAC can feel sudden and disconnected from any social activity. It’s incredibly isolating because friends and family often don't believe the person hasn't been closet-drinking.
Anxiety and the Dissociative Fog
Sometimes the feeling of being drunk without drinking is purely a survival mechanism.
Ever heard of depersonalization or derealization?
When the nervous system is completely overwhelmed by chronic stress or a sudden panic attack, it can "unplug" to protect itself. You feel like you’re watching your life through a movie screen. Objects look 2D. You feel floaty. This "dissociative" state is the brain's way of numbing a perceived threat. It feels exactly like that hazy, disconnected buzz you get after two strong cocktails, but it’s driven by cortisol and adrenaline rather than spirits.
- PPPD (Persistent Postural-Perceptual Dizziness): This is a chronic condition where you feel like you're constantly swaying.
- Neck Issues: Cervicogenic dizziness happens when the nerves in your neck send bad info about where your head is in space.
- Nutrient Deficiencies: Specifically B12. If you're low on B12, your nerves lose their "insulation" (myelin), and your balance goes out the window.
The Role of "Brain Fog" and Chronic Fatigue
We can't talk about this without mentioning the post-viral world we live in now. Long-haul syndromes frequently involve neuroinflammation. When the brain is inflamed, neural transmission slows down. It’s like trying to run a marathon through waist-deep molasses.
You feel "drunk" because your processing speed has tanked.
You forget the word for "refrigerator." You walk into a room and have no idea why you're there. This cognitive dysfunction is a hallmark of Myalgic Encephalomyelitis (ME/CFS) and other autoimmune responses. It’s a heavy, physical exhaustion that wraps around your brain like a wet blanket.
When to Actually Worry
Honestly, if this happens once after a night of terrible sleep, it’s probably just exhaustion. Sleep deprivation mimics a BAC of 0.05% after just 17 hours of being awake. By 24 hours, you’re functionally at 0.10%, which is over the legal limit in every state.
But if you’re getting the feeling of being drunk without drinking frequently, you need to look at the patterns.
Is it happening after meals? (Think: Auto-Brewery or Reactive Hypoglycemia).
Is it happening when you turn your head quickly? (Think: Vestibular issues).
Is it accompanied by a racing heart? (Think: Anxiety or POTS).
Specific red flags include sudden "drop attacks" where you fall without losing consciousness, or if you have a one-sided facial droop or slurred speech that doesn't go away. Those aren't "feeling drunk"—those are potential neurological emergencies like a TIA or stroke.
Actionable Steps to Clear the Fog
If you're dealing with this right now, don't panic. Start tracking.
First, buy a cheap glucose monitor from a drugstore. Test your sugar when you feel "drunk." If it’s normal, you’ve ruled out hypoglycemia. Next, try an elimination diet for a week—cut out refined sugars and fermented foods. If your symptoms vanish, you might have a yeast overgrowth or a gut microbiome imbalance that's messing with your head.
You should also check your hydration—but not just water. You need electrolytes. If your sodium or magnesium levels are trashed, your neurons can't fire correctly. You'll feel dizzy and "weird" until you get those minerals back in balance.
Lastly, see a vestibular physical therapist if the "drunk" feeling is mostly about balance. They can perform the Epley Maneuver or other exercises to "reset" the crystals in your inner ear. It feels like magic when it works. You go from feeling like a bumbling drunk to being stone-cold sober in about five minutes.
Stop Googling symptoms at 2 AM and start a log: what you ate, how you slept, and exactly how the "drunkenness" felt. That data is the only way a doctor can actually help you figure out which of these systems is glitching.
Immediate Next Steps:
- Hydrate with electrolytes, not just plain water, to rule out simple mineral depletion.
- Monitor blood sugar during an episode using a standard over-the-counter kit.
- Schedule a vestibular screening if the sensation is tied to head movement or physical balance.
- Reduce simple carbohydrates for 48 hours to see if the "internal fermentation" feeling subsides.
