I think it's not what time it is, so much as whether something is overkill. For example, reaching for a wine each morning instead of coffee, every day, could be seen as a problem.
But then, coffee is also addictive, so maybe this isn't the best example. Maybe we are all addicts in some way.
But to have a morning Mimosa, Champagne, Sangria or Bloody Mary on a lovely Sunday, or during any lazy day of relaxation, is a wonderful luxury.
