It is possible to forget many things said or done while drunk due to alcohol- induced blackouts, which impair the brain's ability to form new memories. People can lose their "filter" and say things they might regret or not mean, and sometimes they genuinely don't remember what they said or did during intoxication. However, being drunk doesn't provide a free pass for behavior, as people are still responsible despite memory loss. Blackouts are different from regular forgetting; the events may feel like they never happened to the brain because the memory was never recorded in the first place. Emotional memories might still linger, but factual recall is often lost.
So, forgetting what was said when drunk is possible, but it depends on the level of intoxication and whether a blackout occurred.
