I don't drink very often, but when I do I like Mike's Light Lemonades. They are under 100 calories per 12/oz bottle..kind of taste like a wine cooler but not so sweet. Light beer isn't too bad either.
Anything w/ mixers you should avoid, mostly because the mixers are usually so high in calories. If you drink diet soda, a hard alcohol mixed w/ that isn't too bad either.
Take care, Lynn M.
