Withdrawal refers to the process of cutting out or cutting back on addictive substances or behaviors. It is a physiological response to the sudden quitting or slowing of use of a substance to which the body has grown dependent on. Withdrawal symptoms can vary in type and severity depending on the substance used, how long it has been used, age, physical health, psychological characteristics, and method of withdrawal. Common symptoms of withdrawal may include:
