Hey, gin and tonic was invented as a way of making anti-malaria medication (quinine) palatable in British colonial India.
I always tell Mrs. Zap I'm drinking them to ward off malaria AND scurvy, so therefore, it's healthy. Plus, it's quite refreshing during our "Hotter than Satan's Balls" summers.
And as to some folks belief it is unpalatable, I recommend Broker's gin. To me, it has more than a hint of Rosemary. Sounds weird, but it's really good.
