I started some medication that made my desire to drink disappear. After a while, I tried having a beer with friends and just got an overwhelming desire to nap. My tolerance had disappeared. So I don't really drink anymore, but I used to brew my own beer and occasionally drink way too much. I've also enjoyed not having to worry about being able to drive if an emergency happens etc. One of the big downsides is how obnoxious drunk people can be when you're sober.
