I can drink a whole bottle of Vodka no problem

So lately, I’ve been struggling with mental health. I rarely get on this app, especially for advice, but I drank a whole bottle the other night & it’s been continuous . It used to be a couple times a week to only weekends (thankfully) I get hang overs but it went from being super sick to just being dehydrated & being able to get over it, no big deal imo. Is my tolerance increasing? Is this bad? I used to be a lot worse but still I have high tolerance when it comes to drinking since it’s been years I’ve drank.
