ADVICE

Measure What A 'Drink' Actually Is

  • Measure alcohol amounts because people consistently underestimate drink sizes.
  • Use standard measures: 1.5 oz 80-proof, 1 oz 100-proof, ~4.5 oz wine, 12–16 oz beer.
ANECDOTE

  • That habit meant he was actually drinking the equivalent of six standard drinks daily.
