Day drinking ok if not done to get drunk?

To celebrate something, sure! Having a beer on an afternoon off because it's hot, sure! Starting at 9am just because you have alcohol, no.

Like a drink at a luncheon or something? Sure.

Why not.

not really... i drank for year not to get drunk and it still gave me a bad case of arteriosclerosis.

Keep telling yourself that. It does depend on what hand how much you are drinking.

the headaches to come about ....
