What’s the point of drinking?

I turned 21 today, so I thought I would buy an alcoholic beverage just for fun. I bought a beatbox and I had no idea how strong it was so I chugged it. I was thirsty and the package was so misleading, it came in the package similar to coconut water, so I drank it as such. Now couple hours later. As I am writing this, I am in such a miserable state. My head is going to explode and my stomach hurts like hell. I guess it was my fault, but the packaging is seriously misleading. Anyways I’m just here wondering what the point of drinking is, I didn’t feel good at all, and I am just dying right now.
