I Drink Coke Like Most People Drink Water

I can't seem to get through a day without at least drinking 2 or more Coca-Cola. I don't know what it is but the addiction is so bad that when I'm in a bad mood, my kids say "Mommy just needs a Coke.". True enough, I calm down and can relax easier. I hope I'm not the only person with this craving. I don't want to end up with kidney problems but it tastes so good cold. Especially in Texas weather when it's hot outside, a Coke is sooo good going down my throat. I need help.
