Diet soda or tonic water. Seriously, anything else you add (juice, real soda, etc.) is going to make each drink have more calories & carbs (the bad ones too - sugars) than beer, so unless you go with diet, you're doing yourself no good. You can try tequila though; the good stuff goes down smooth, and the cheaper stuff goes down... No mixing required 😉 Not sure how people drink vodka anyway, stuff's nasty. Might have something to do with my first experience, at 17, having something to do with about a pint of the stuff, and various other liquors 😉
