After 24 hours, alcohol has left your system. You can’t get any soberer (is that even a word?) than that. You may feel the effects of detoxification for up to 1 week or more after alcohol is out of your system. Withdrawal symptoms begin within 8 hours after your last drink. Within 24 to 72 hours, the symptoms reach maximum misery. After 5 to 7 days, the symptoms lessen in intensity. Beyond 1 week, the psychological effects may continue for a lifetime if untreated. Associated with this timeline (depending on your level of consumption) is a list of symptoms that traverse 3 stages. Stage 1 includes nausea, insomnia, and stomach pain. Stage 2 involves high blood pressure, high temperature, abnormal heart rate, and confusion. Stage 3 gets even worse with fever, seizures, hallucinations, and observable agitation. The last stage can be dangerous and potentially life-threatening. Even if you have only been drinking for a short time (weeks) or for many years, detoxing at home alone is not advisable. Seek professional help if you plan on stopping drinking.
