What's your poison, and how much do you consume?
I'm not a pop (soda) drinker. I'll have a Pepsi on Friday nights, which is pizza night around here.
My oldest boy and myself are water drinkers. I have a 5 gallon water cooler in the kitchen, plus we have an RO system. I've pretty much cut all caffeine out of my diet, and for health reasons, and I feel better for doing so. As for my wife and other kids - if they ever stop drinking Pepsi products their stock will drop sharply.
