Blue Sky "Free"
Man, I've been guzzling this stuff lately. It's kinda pricey at 89 cents a can, but it's GOOD stuff. I've only seen it at health food stores. Trader Joe's may carry it too. It is sweetened with erythritol and stevia. No aspartame or splenda, all natural flavors. The Cola actually contains Kola Nut oil!
