We stopped buying soda about a year ago and I haven't missed it a bit. I usually drink plain water, Crystal Light or herbal teas throughout the day. I do occassionally have a diet soda at picnics or other family gatherings; however, I try to stick with Diet Rite because it is the salt in soda that really gets me. My body is prone to tons of water retention and drinking soda with a lot of sodium in it keeps the scale from moving for me.
I am amazed at how much money we save each week when we cut soda out of our grocery budget.
I don't miss the caffeine because I've yet to have the courage to give up my 1-2 cups of morning coffee.
What I love though about not having soda in the house is that my 3 and 5 year olds will ask for water when they are at a friend's house or at a restaurant. They never consider asking for anything but milk or water and would rather eat fruit than ask for fruit juice (which I also do not keep in the house).
