Drinking too much soda

I've decided to do something that will be a win-win situation for me no matter what I do. I've been drinking waaaaay too much soda recently and not enough water. I don't know why, but I have. So, now when I drink soda I'm going to put $1 aside in an envelope to put into my savings account. If I spend money on and drink a soda, I'll have to pay myself. If I don't, I've saved the money and calories.

I'm usually a big water drinker, but for some reason I have really slacked off in the last month or so. I used to drink 9-10 large glasses of water a day, and now I'm only drinking about 2-3. Maybe I just drink more water in warmer weather, I don't know.

So, I already had some soda for some caffeine this morning, so that's $1 in an envelope.
