Recent research put alcohol as the most toxic drug ahead of cocaine and heroin stating that far more lives are destroyed because of alcohol than other substances. If you have been drinking in large quantities every day for a long time you will experience alcohol withdrawal symptoms if you quit all at once. Remembering about the unpleasant memories about when you became drunk would help you to motivate yourself to quit alcohol totally. You will begin to realize that people do not need to drink alcohol to enjoy life, and that life can be pleasant without alcohol.
