What does it feel like to be drunk?

I have never been drunk. That’s not to say I haven’t drank alcohol, just that I haven’t had enough to be drunk, or maybe that I have a really high alcohol tolerance. Anyway, what does it feel like to be really [actually] drunk?

It would be great if you could explain in as much detail as possible, and possibly explain the steps leading up to drunk-ness, so I can stop before I throw up!
