I don’t get it

I drank a whole bottle of red wine (19% ABV) and then half of another bottle (10% ABV).
I also took diazepam, although I know that’s important, so let’s focus on the alcohol for a moment.

And somehow I’m not drunk. Not even tipsy. I can walk straight, speak normally, and I don’t feel particularly impaired. I’m just sitting here painting.
Wtf is wrong with my liver? 😭
I once drank a whole bottle of vodka too (over a long period of time, while eating and dancing), and then had a flight at 6 a.m. that I took without any issues.

Does anyone else have a similar experience? Is it possible to have a high tolerance without actually feeling drunk?
