Alcohol just makes me sleepy

I’m 23 and I had never drunk anything before.

I decided to try vodka, tried it several times and it doesn’t take away the anxiety which is why I’m drinking it. I just go to sleep for an hour and when I wake up I’m not drunk anymore. It’s not a pleasant or refreshing sleep.

People drink alcohol to feel happy and relaxed. I don’t get any of those feelings. What am I doing wrong? Lyrica (pregabalin) is 100 times better than this.

Also just to be clear I am 100% aware of the dangers and ethics and whatever.
