I stopped drinking soda by replacing it with fruit juices. Not store bought pasteurized crap, but real juice made from real fruits and veggies. Figure out how much money you are spending on soda, and when you get to $150, head up to the local Target store and buy a Jack LaLanne Power Juicer Pro. The only store bought juice I drink is Ocean Spray cranberry, but only because cranberries are not in season, and because it has no high fructose corn syrup.
I also weaned myself off of Starbucks bottled Frappacino when I realized I was spending almost a $100 a month on the stuff. Now I simply drink real coffee, made with good quality freshly ground beans, and I add some sweetener and some French Vanilla creamer.
I could never give up caffeine, and I refuse to believe those people that say it is bad for you. Those are the same people that want me to stop enjoying all the foods I like. I’d rather eat and drink what I like than to go without because some guilt trip food guru says so.
Everything you eat is going to kill you sooner or later. Why be miserable?
