Alcohol can certainly change your values. If it didn't, alcoholism wouldn't be considered a problem.

I have seen plenty of people restructure their value systems to put alcohol on top. Complex constructs are created to excuse behaviour, reprioritize, etc. making alcohol the priority.

Many times family, friendships, work, personl hygiene are slowly ranked lower than the almighty bottle. People that don't drink are considered "square" and why can't people understand that you need a few drinks to "take the edge off"?

That's a value-system being destroyed by alcohol. It doesn't happen in all people, or even most, but it does happen.
