Withdrawal reaction will occur after self-quitting, if the withdrawal reaction symptoms are mild, then it can disappear by itself within 1~2 weeks, but if the withdrawal reaction is more serious, then you should not self-quit to avoid danger, and other physical changes caused by drinking alcohol may take a longer time to subside. Withdrawal reactions such as hand tremor, nausea, sweating and anxiety may occur after quitting drinking, which usually lasts for 1~2 weeks to subside; however, patients with severe alcohol dependence may experience symptoms such as delirium tremens and blurred consciousness, and this kind of patients should not quit drinking on their own, and need to do so under the guidance of a doctor to avoid any adverse consequences. Long-term alcohol consumption may also lead to gastric ulcers, alcoholic fatty liver disease, and increase the risk of hypertension and other cardiovascular diseases, which may take a longer time to recover, or even fail to recover, after quitting drinking. If you experience any discomfort during the withdrawal process, please seek medical attention.
