Drinking a bottle of whiskey a night

So I do drink a lot, and not always every single night but probably 4-5 nights a week. Because of this I have a pretty damn high tolerance. So at this point I can get to the bottom of a bottle, but I’ll def be pretty drunk, weirdly enough extremely coherent. I’m just wondering if this is excessive, and what do to honestly. I mean I can go days without drinking no problem, no crazy consequences, but I just eventually give in and drink again. Any comments ideas or opinions? Thanks guys
