I can't say I know the answer to any of it.

Sometimes, if it is something celebratory going on, I might have a drink while out dining with friends. Thing is, if I were at home having a normal supper, there would generally be no alcohol.

The only time I have had alcohol for breakfast was when it was a Mimosa (champagne and juice) for New Years Day.

As far as lunch goes during a work week, my company can send anyone for a random drug screen and if you have alcohol in your blood during work hours, you can kiss your job goodbye......so that is something I have never gambled with. :)
