Hi. Sometimes, soda craving is a misinterpretation of what you're body really needs. It's not the soda that your body is craving. It's the calcium. Your body needs more calcium. Try taking some time, a month or two, supplementing you calcium intake. You might want to take supplements, milk or healthy vege's such as brocolli rich in calcium.

I'm a soda addict before. But I found out this one thru a program I am in now. It's 30 Day Sugar Free by Barry Friedman. If you have more problems about your sugar intake, just give me a hit. I share what I have learned to you
