Alcohol has always been linked to depression.  Since it is a depressant, it usually ends up "deadening feelings" in people who consume it regularly.  I usually refer to those moments as blackouts, but to each his own.  Now a new study shows that non-drinkers may be more depressed than people who drink.  The study showed that people who abstain from alcohol have more anxiety and are at a higher risk for depression.  Here at the office, we refer to this as the "No S--t" study.
