I'm like you Tan, love my beer (Miller Lite here).
But I also missed wine coolers on hot afternoons, so I found a really cheap and low-carb way to make them. (Most of the recipes I found were more like sangrias than coolers.)
However, you have to promise not to laugh.
I bought a bottle of Boone's Farm Watermelon flavor wine (doesn't that bring back a few memories for some of us?)
Mix 2 parts Boone's Farm (or any other really, really cheap flavored wine) to 5 parts Diet Sprite.
It's so refreshing! The watermelon is my favorite, followed by strawberry. The overall count in a bottle of cheap stuff is higher, but when you break it down into servings, it's very low. And a heckuva lot cheaper than your typical high-carb cooler.

- their margarita mix is another "lifesaver" if you're low-carbing.
