Why do I blackout so easily?

Do other people black out regularly? I’m not sure why but since after the pandemic every time I drink I can’t remember moments of the night the next morning and it’s not like I’m drinking a lot. If I drink 1 shot and a cocktail I’ll black out. The only way I don’t black out if if I take only 2 shots or only about 3 cocktails but sometimes people offer me shots when I’ve taken a cocktail and I take it then I’m out 🙁
