You can't make this up:
Winston Churchill loved his booze. He drank Champagne at every meal, Scotch all day long and brandy in the evening. He once asserted that “hot baths, cold Champagne, new peas and old brandy” were the four most important things in life. And biographer William Manchester wrote in The Last Lion that there was “always some alcohol in his bloodstream.”
It's good to know that the rich and powerful needed prescriptions like the rest of us.
It was far from only the powerful, although I guess money had a bit to do with it. The New Orleans Pharmacy Museum has a wide selection of prescription forms like this for regular old US citizens (not just visiting dignitaries), and the ills the prescription liquor "cured" are all equally hand-wavy.
We shall defend our alcohol, whatever the cost may be. We shall drink on the bridges, we shall drink on the playing grounds, we shall drink in the fields and in the streets, we shall drink in the hills; we shall never be sober.
