Can’t get psychologically drunk?

First I got drunk was when I was 17, it was the most beautiful feeling in the whole world, I of course went sober, and never sipped alcohol ever since then. But now being at 28 I tried alcohol, and it isn’t hitting the same as it did when I was 17??? Sure I will stumble around, and be more confident or talkative than usual but it just is not the same, I wonder if it’s even the same drug. I drink a whole bottle of whiskey, and I’m still sober mentally. I tried gin too, and beer but it’s just not making me feel the same as it did before??? Is it part of getting older or what
