Tonic water, with some gin.
Me too, with or without the gin. Lime is too hard on the old tum-tum now. Prefer Schwepps when I can get it. Fever Tree is awesome, but the price! I save that for the good gin. Store-brand tonic universally sucks.
Ginger ale is good, with or without dark rum. Schweppes again, with Appleton Estate 12year-old.
