You might consider giving up the soda for a stout beer a day. Or perhaps a glass of wine. Maybe even a Margarita (if you're daring). A bit of alchohol is healthy, I've heard.
...and it's delicious too.
I drink either a beer, or a glass of wine, every day.
The wine, I drink for my health. The beer, I drink because I like to go to the ice house and see my friends for a bit.
