It's already spring and summer is very near, what's your favorite thirst-quencher during summer?

Unfortunatly, due to a low sodium diet, my favorite thirst quencher is lemonade made with Splenda. Diet Rite is the only sodium free soft drink I have found and I keep that on hand.

True®Lemon crystals packet in a glass of water or a couple of them in a reusable water bottle. I also enjoy apple cider vinegar in a glass of water.

I don't drink coffee at all- but I am a diet pepsi addict. I also make a pitcher of cool water w/ a squeezed split lime in it most summer mornings and have it drank-up but sundown.
