Attempting to go through the detox process on your own is never a good idea, especially if you have a substance use disorder that involves alcohol or harder drugs like methamphetamine or heroin. The detox procedure can put a huge amount of stress on your body, and withdrawal symptoms can be extreme. With substances like alcohol, there is a real risk of seizures, making the process a life-threatening one if attempted alone. At a treatment facility, you can get the medical detox you need to avoid the worst of the withdrawal symptoms and cravings associated with the substance you misused.
