The Central Nervous System gets depressed by alcohol, causing feelings of relaxation and euphoria. The human body tries to maintain balance, because of which it signals the brain to create more neurotransmitter receptors to stimulate the nervous system. As one stops drinking, it takes away alcohol from all the receptors that were present originally but also from the new receptors that the body has made. As a result, the nervous system becomes overactive and starts showing different withdrawal symptoms.

Daily drinkers ought to be more cautious than people who drink occasionally. Major alcohol withdrawal symptoms include irritation, confusion, fever, paranoia, and hallucination. Other symptoms may include anxiety, nausea, rapid heartbeat, sweating, and tremors. There are multiple other risk factors, that determine how long alcohol withdrawal may take.

Some DT associated risk factors include:

  • Low levels of potassium and sodium
  • Old age at the time of withdrawal
  • Dehydration
  • History of DT and seizures
  • Presence of brain lesions
  • Abnormal liver function
  • Use of other drugs

People with other health issues such as liver or heart problems should directly consult a doctor and stop drinking alcohol immediately. It takes at least seven days to detox alcohol from the human body. However, for daily drinkers, it may even take up to a month to heal from alcohol withdrawal symptoms.
