Soda is too tasty

I've been looking around at the best weight loss supplements. Though, in my case, the best idea would be to stop eating so much junk food and drinking so much soda. But they make it soooo tasty! Ooh, maybe there's a supplement that will make soda taste nasty. Then I would have to find a different way to get the caffeine into my body in the morning. Hmm...maybe they could just make water taste more like soda ^_^
