How Long Does The Detox Phase Last

Going through detox is the first step in drug or alcohol addiction recovery. Detox is the detoxification process of the chemicals from alcohol and drugs leaving your system. It’s physically uncomfortable and can be emotionally overwhelming, but it’s the critical first step on your recovery road. The good news s that the detox phase doesn’t last very long – if you can hang on through the first few days, especially if you opt for supportive medical detox, then many of the worst withdrawal symptoms wane, and your body is free from the addictive substance.

How Long Does the Detox Process Last?

It depends on the substance or substance you’re getting treatment for, and it can last as little as 72 hours or as long as a couple of weeks. At East Point Recovery Center, we offer intensive, supportive drug and alcohol rehabilitation and can help you find the right detox facility before starting one of our evidence-based rehab programs. Many of our clients are referred by our counselors and begin the program right after detox.

How Long the Detox Period Lasts, By Substance

While many of the most serious withdrawal symptoms, like headaches, vomiting, and diarrhea, may make you feel like you’re dying, elevated heart rate and rapid dehydration can actually be life-threatening. If you’re detoxing from two substances at the same time, then you may have mixed symptoms or more intense symptoms. Complications from alcohol and benzodiazepine withdrawal can be deadly, so medical supervision is necessary if you’re detoxing from one of these.

Medically supervised detox for all addictive substances is available, though, and can help ease the physical pain of early withdrawal. And, medical detox facilities are usually safe and supportive, so you can rest and sleep as much as you need. Your body has been through a lot with your addiction, and healing takes a lot of energy out of you. Medical detox facilities can provide the nutrition you need while you’re detoxing.

Changes in Your Brain During Detox

When someone is addicted to alcohol or drugs, their brain chemistry changes, instead of relying on the natural chemicals in the brain for elevated mood or mood regulation or feelings of joy or accomplishment, an addict’s brain relies on the substance. Their brain reduces the production of chemicals like serotonin and dopamine because the drugs or alcohol they use to act on the same pleasure receptors as those hormones.

When someone stops using drugs or drinking, it can take a while for the brain to resume hormone production. The first few weeks and months after detox can leave someone feeling a lack of joy or pleasure in activities they once used to like – many people describe the first weeks in recovery as profoundly “meh.” The good news is that your brain will heal if you stay sober and resume creating mood-boosting and regulating hormones.
