Is it true that when your drunk you say what want to sober?

That's a common saying, but it's not entirely true. While alcohol can lower inhibitions and make people more likely to express their feelings, it doesn't guarantee they're revealing their true, sober desires. Alcohol can also impair judgment and lead to saying things that are regretted later, things that wouldn't be said sober. So, it's a simplification; sometimes it's true, but often it's not.
