Is alcohol really as bad as people make it out to be physically?

I turned 21 in December and while I’ve drank on and off my whole life, the past 6 months I’ve drank pretty heavily. At least more than the CDC guidelines. But I’m so big coming in at 6’10” and 256 lbs that it naturally takes 4 drinks for me to feel anything. I also have a really high natural tolerance. Over the course of the 6 months, I have had a month long break and a 2 week long break and had no withdrawal symptoms or anything. Mentally I’m fine, I am a college student majoring in computer engineering but I made all As last semester while slamming liquor every night. No arguments with family or my girlfriend, everything has been fine.

But, I want to know specifically how alcohol affects you physically because it is a lot harder to tell. As far as I know, I am perfectly healthy; moderate resting heart rate, BP is fine, little to no hangovers (albeit 1 really bad one when I first started), urinary and intestinal tract is (I think) fine. Maybe a little more acid reflux than usual but not much. I primarily find that dark liquors give me less hangover than clear liquor like vodka, so I drink a lot of bourbon and whiskey; tend to stray away from beer even though I love one from time to time because it affects my blood sugar in the morning. Other than that, I can’t think of how else alcohol could affect my body other than my liver

So I guess my main question is, how do I know if my liver is okay or being affected? And are my other vital organs being affected or is it for the most part just a thing that happens over a long period of time and you don’t notice? I keep seeing that alcohol is “the worst drug” for every system in your body but I’m not seeing any consequences at the moment. I would think from 6 months of heavy drinking I’d at least see one negative physical consequence but I have yet to
