Alcohol doesn’t feel as euphoric as it did when I first started drinking

About 4 years ago when I first started drinking (I’m not an alcoholic I rarely drink) but when I first started I was almost 100% sure alcohol was my drug of choice, I became insanely confident and felt on top of the world the first 2 ish years of drinking every now and then, but now it makes me feel so lethargic and dizzy and all around is barely euphoric unless I’m having an amazing day already or something. Does anyone know why this is or has experienced this themself?
