Does drinking worsen every mental health issue?

Yes! Drinking alcohol moderately (up to 2 drinks/day for men) will probably not cause problems. Becoming intoxicated complicates existing mental health issues by disrupting sleep cycles, destabilizing mood, and many other effects. It also induces mental health issues of its own -- especially if you become habituated to drinking, even in binge form. You can also make really bad decisions when drunk.
