Withdrawal symptoms can be a difficult aspect of overcoming addiction, both for substance and behavioral addictions. With substance addictions, the physiological aspects of withdrawal can be extremely uncomfortable, feeling like a bad flu, or can even be life-threatening. For this reason, it is a good idea to talk to a doctor about the best way and the best place to quit a substance.
Fortunately, most of the acute symptoms of withdrawal pass within a week or two of quitting. However, some people who quit an addiction find that certain withdrawal symptoms seem to go on and on. This is known as post-acute withdrawal syndrome, and it can go on for weeks, months, or even years in some cases.
The risk of dying from an overdose is extremely high if you have been through withdrawal, as your tolerance of the drug will be much lower than it was before you quit. Make sure you have someone with you if you decide to use again.
In addition, addictions can sometimes mask underlying mental health problems, such as anxiety, depression, sleep disorders, and even psychosis. If you are feeling blue or agitated, or you are concerned that the world or other people seem strange or upsetting since you quit, talk with your doctor. There are effective treatments for these problems that are much more effective than addictive substances and behaviors.
