Wondering if anyone else has experienced this?

Ive been drinking since I was quite young (11-12) and up until lately only ever really blacked out 4-5 times but for the past 1-2 years been blacking out maybe 5-6 times a week. It used to take so much liqour to black out & nowadays it doesnt take much at all. Wondering if anyone else has experienced anytjing similar? As I would think after more time It should take longer rather than way less alchool to cause a blackout…
