Alcohol addiction and getting clean

Does getting clean make much of a difference as far as the voices?

They were more clearer for me, but not less talk.

I read a study that said 2 drinks a day makes people live longer so I had 2 beers a day for 6 months. I quit it cold turkey pretty easily. but I thought less clearly, now I just drink if something awesome is on tv.

I rather give up smoking than drinking.
