Alcohol withdrawal is not usually symptomatic the morning after an alcoholic decides to stop drinking. In most cases, in fact, symptoms take between two and four days to peak. Initially, these symptoms might start out rather mild, and they might feel like a really, really bad hangover. They could include a loss of appetite, profuse sweating, shakiness, nausea, and vomiting. These physical symptoms will often lead to behavioral symptoms, including severe agitation, a shortened temper, anxiety, and extreme restlessness. A combination of these withdrawal symptoms are uncomfortable enough to lead an alcoholic right back to drinking. For this reason, admission to a structured and closely monitored detox facility is necessary. If a withdrawing alcoholic is in the throes of withdrawal, and he or she is attempting to detox alone without medical assistance, the chances of relapses are exceedingly high. Additionally, alcohol withdrawal can be life-threatening. The above-listed symptoms are relatively moderate, though symptoms of alcohol withdrawal can be extremely severe. These life-threatening symptoms include tremors, extreme disorientation (which can lead to serious accidents), seizures, increased heart rate (sometimes leading to heart attack), suicidal ideation (resulting from extreme depression), and coma.
