I used to go in my teens(not a lot just here and there) and then college started and my life went pretty much downhill. They can be fun for the first few hours but after a while you start feeling pretty much beaten and tired. It can be quite exhausting.
I have, and for me was lame ass boring, I hate any place where the music is too loud to have a conversation, and the most of drunk people are not fun, they're plain obnoxious. But it's up to personal preferences, some people love those environments.
