Cover art for You and Tequila lyrics by Kenny Chesney

This song is actually about both unrequited love and drug/alcohol abuse. He misses his wife or girlfriend, so he drinks. He quits drinking and tries to move on, most likely through a twelve step program. The words "One is one too many, and one more is never enough." Come from the Alcoholics Anonymous Big Book.
