Opiate withdrawal typically begins 6 to 12 hours after the last dose, peaks between 24 and 72 hours, and largely resolves within five to seven days. Symptoms include muscle and bone pain, cramping, nausea, vomiting, diarrhea, sweating, watering eyes, goosebumps, restless legs and severe insomnia. It is rarely life-threatening, but the drop in tolerance afterward carries real overdose risk.
Timeline
How opiate withdrawal progresses
Short-acting opiates follow this course. Extended-release formulations and methadone run considerably longer.
| Stage | When | What happens |
|---|---|---|
| Early | 6–12 hours | Anxiety, restlessness, yawning, watering eyes, runny nose, sweating. |
| Building | 12–24 hours | Muscle and bone aching, cramping, goosebumps, chills, insomnia setting in. |
| Peak | 24–72 hours | Nausea, vomiting, diarrhea, deep aching, restless legs, no sleep at all. |
| Declining | Days 3–5 | GI symptoms settle, aches recede, appetite begins returning. |
| Resolution | Days 5–7 | Acute withdrawal largely over for short-acting opiates. |
| Post-acute | Weeks | Sleep, energy and mood normalizing. Cravings and overdose risk both highest. |
Symptoms
What people actually report
Bone and muscle pain
Deep aching through the limbs, back and legs. The symptom most often described as unbearable and the one that most often ends unsupervised attempts.
Restless legs
A compulsion to move that makes lying still impossible, worst at night. Compounds the insomnia badly.
Gastrointestinal
Nausea, vomiting, diarrhea and cramping through days two and three. Dehydration is the practical risk here.
Autonomic
Sweating alternating with chills, goosebumps, runny nose, watering eyes, raised heart rate and dilated pupils.
Sleep
Frequently total insomnia for the first two or three nights. Near-universal and among the most persistent complaints.
Psychological
Anxiety, agitation, low mood, and cravings that intensify rather than fade across the first fortnight.
What is actually risky
Which parts warrant attention
Opiate withdrawal will not kill you. Three associated things can cause real harm.
Dehydration. Days of vomiting and diarrhea with little fluid intake leaves people genuinely depleted, and that is the most common medical complication of an unsupervised withdrawal.
The tolerance drop. Within days of stopping, tolerance falls dramatically. Returning to a previous dose after a week is how most post-abstinence overdoses happen. Keep naloxone at home.
Precipitated withdrawal. If you are considering buprenorphine, timing matters enormously. Taken too soon it strips the receptors abruptly and produces something far worse than what you already had — see fentanyl withdrawal for why this is harder to judge when fentanyl is involved.
Getting help
Days two and three are why unsupervised attempts fail
Comfort medication and, where appropriate, buprenorphine change the severity of the peak substantially. Our clinics in Woodstock and Hiram run to 7:00 PM on weekdays and open Saturday and Sunday mornings.
Common questions
Opiate withdrawal, answered
What does opiate withdrawal feel like?
People consistently describe it as the worst flu of their life with restlessness on top. Deep bone and muscle aching, cramping, sweating, watering eyes, goosebumps, nausea and an inability to keep still or sleep.
How long does opiate withdrawal last?
For short-acting opiates, symptoms begin 6 to 12 hours after the last dose, peak on days two and three, and largely resolve within five to seven days. Sleep and mood take weeks longer.
Is opiate withdrawal dangerous?
Rarely directly life-threatening. The real dangers are dehydration from prolonged vomiting and diarrhea, and the sharp fall in tolerance afterward that makes relapse potentially fatal.
What is restless legs during withdrawal?
An almost unbearable compulsion to move the legs, worst at night. It is one of the most commonly reported symptoms and among the least tolerated — the reason many people describe being unable to lie still for days.
Why can I not sleep at all?
Insomnia during opiate withdrawal is close to universal and often total for the first two or three nights. It compounds everything else, which is why sleep support is a standard part of any protocol.
When is the worst part?
Days two and three for short-acting opiates. If you can get past 72 hours the physical symptoms decline sharply — which is precisely why so many unsupervised attempts fail on day two.
Do the symptoms come back after they stop?
With short-acting opiates, generally not. With fentanyl they do, because it stores in fatty tissue and releases in waves. If your symptoms recede and return, that is a strong sign fentanyl is involved.
What are post-acute symptoms?
Sleep disturbance, low energy, flat mood and cravings persisting for weeks after the physical symptoms resolve. This is the window where most relapse happens.
Can medication make this easier?
Substantially. Buprenorphine where clinically appropriate reduces peak severity markedly, and clonidine, anti-nausea medication and sleep support handle the rest.
Why do I feel worse than people describe?
Dose, duration and which opiate all change severity considerably, and long-acting formulations produce a longer, flatter course. It is also worth considering whether fentanyl has been present.
