Let’s be honest: the idea of stoppingdrinking can feel terrifying. It’s not just about the lifestyle change; it’sthe physical fear of what happens when the alcohol leaves your system. If youor a loved one are considering this step, you likely have one burning question:What exactly am I going to feel, and for how long?

At Regal Treatment, SouthernCalifornia’s premier drug and alcohol addiction treatment facility, we believefear shouldn't be a barrier to recovery. Understanding the timeline of alcoholwithdrawal removes the mystery and highlights why professional, personalizedcare is the safest path forward.

Here is a day-by-day breakdown of whatthe body experiences during detoxification and why medical supervision isnon-negotiable for your safety.

Why Withdrawal Happens: The Science in Simple Terms

Before we look at the clock, it helps tounderstand the why. Alcohol is a depressant, meaning it slows down yourbrain's communication pathways (specifically by enhancing a chemical calledGABA and inhibiting glutamate).

When you drink heavily for a long time,your brain adapts by constantly hitting the gas pedal to counteract thealcohol’s braking effect. When you suddenly stop drinking, the"brakes" are gone, but your brain is still flooring the gas. This chemicalchaos causes the shakes, anxiety, and physical symptoms known as withdrawal.

The Acute Phase: The First 72 Hours

This is the most critical window. Whileevery person’s physiology is different, the timeline generally follows apredictable pattern.

Stage 1: The Onset (6 to 12 Hours)

Symptoms often begin before alcohol hascompletely left the bloodstream. You might wake up feeling"hungover," but the feeling doesn't fade, it intensifies.

●      Physical Signs: Mild tremors (the "shakes"), headache, nausea, sweating, andheart palpitations.

●      Mental Signs: anxiety, irritability, and vivid dreams.

●      What Helps: Hydration and a calm environment are key here, but this is the signalthat medical monitoring should begin.

Stage 2: The Peak Escalation (12 to 24 Hours)

For many, this is where the reality ofdependency sets in. The brain's hyperexcitability increases.

●      Hallucinations: Unlike the "pink elephants" of cartoons, this is serious.About 25% of patients may experience "alcoholic hallucinosis",seeing, hearing, or feeling things that aren't there.

●      Confusion: You may struggle to focus or remember where you are.

●      Vital Signs: Blood pressure and heart rate often spike. At Regal Treatment, ourclinical team monitors these vitals constantly to prevent complications.

Stage 3: The Danger Zone (24 to 48 Hours)

This is the window carrying the highestrisk for seizures.

●      Generalized Tonic-ClonicSeizures: These can occur without warning, even inpeople with no history of epilepsy.

●      Note on Safety: This specific risk is why "detoxing on a friend’s couch" isdangerous. In a licensed facility, medication-assisted treatment (MAT) is usedspecifically to raise the seizure threshold and keep you safe.

Stage 4: Delirium Tremens (48 to 72 Hours)

Only about 3-5% of patients experienceDelirium Tremens (DTs), but it is a medical emergency.

●      Symptoms: Severe confusion, severe agitation, fever, profuse sweating, and rapidheartbeat.

●      The Risk: Without medical intervention, DTs can be fatal due to cardiovascularcollapse.

●      Our Approach: We prioritize preemptive care. By using appropriate medications early,we aim to prevent a patient from ever reaching this stage of severity.

The Long Tail: PAWS (Post-Acute Withdrawal Syndrome)

Once the acute physical danger passes(usually after 5–7 days), the brain still needs time to heal. This phase, knownas Post-Acute Withdrawal Syndrome (PAWS), can last for weeks or months.

●      Symptoms: Sleep disturbances, mood swings, fatigue, and variable energy levels.

●      Treatment: This is where Regal Treatment’s focus on personalized care shines. Wedon't just treat the detox; we build a therapy and nutrition plan to supportyour brain's long-term repair.
