Content: How Does Alcohol Cause Blackouts? If you usually stop after a drink or two, then you’ve probably never had an alcohol-related blackout. They usually happen when people drink too much too fast. Consuming excessive alcohol can lead to gaps in memory. Those gaps form because the alcohol prevents short-term memories from becoming long-term memories. Sometimes, people who drink too much may have spotty memories of what happened the night before. Other times, someone who’s heavily intoxicated may lose hours of memory. If the memories never formed in the first place, there’s no way to get them back. Who’s at Risk for Alcohol-Related Blackouts? People who binge drink -- consuming four to five drinks in about two hours -- are more likely to have alcohol-related blackouts.
