Hello and welcome to HealingWell,
An alcohol induced blackout occurs when a person drinks so much alcohol that his or her long term memory is impaired. Blackouts are not to be confused with "passing out", which is when a person becomes so intoxicated by alcohol that he or she simply loses consciousness. Most blackouts are caused by the rapid ingestion of a large amount of alcohol in a short period of time. In other words, someone who quickly downs several shots of alcohol within an hour is more likely to experience a blackout than someone who slowly drinks alcohol over a longer period of time. This is true even if the person who drinks more slowly ends up ingesting more alcohol and becomes more intoxicated.
Blackouts are dangerous for many reasons. For one thing, people who are experiencing a blackout are still conscious. Alcohol use tends to lower a person's inhibitions and impair judgment, which may cause them to engage in high risk activities like drunk driving, sexual promiscuity, fighting, or committing crimes. These high risk activities may lead to any combination of serious injuries, chronic diseases, legal problems, or death. Moreover, a person who is experiencing a blackout may not have any control over their impulses.
The only way to completely avoid alcoholic blackouts is not to drink alcohol.
I think you are right to be worried about your black outs so please do seek medical help.
