Tremors feel like your body is vibrating from the inside out. Your hands may quiver when you try to hold them still, sometimes worsening the more you focus on it. It can feel embarrassing or scary—like you’ve lost control of your muscles. Even simple tasks like using a phone, drinking water, or buttoning a shirt may feel clumsy or impossible.

This feels like your internal thermostat is malfunctioning. You might break into heavy sweats suddenly, even in a cool room. Sweat can bead on your skin, soak clothing, or drip down your back. It can feel sticky, uncomfortable, and hard to manage, as if your body is constantly overheating or purging something.

Withdrawal nausea is often a deep, unsettled churning in the stomach that refuses to go away. Food can seem unappealing, and even the thought of eating might make you queasy. Some describe a rolling or sloshing sensation, as if their stomach is full of rocks or acidic liquid. This can escalate into vomiting, which can bring temporary relief but usually returns quickly.

Seizures are one of the most dangerous withdrawal symptoms. They often strike suddenly, without warning. Most people lose consciousness and don’t feel the seizure itself—but afterward, they may wake up extremely confused, sore, or exhausted, with no memory of what happened. It’s a medical emergency every time.
