I managed to go one week without drinking very many calories, and no sodas at all. I drank a fair amount of unsweetened tea with lemon, which is good for 10-15 calories per serving. Pretty negligible really, especially compared to 140 calories per 12 oz.
This only led me to one pound of weight loss, even by staying under my calorie allotment, and by playing hockey twice in the week. No matter, I feel better than I did just one week ago. I was getting to where I just felt physically sluggish overall. Physically, that feeling is gone.
Mentally, there are other things I need to address. Mainly, I just don't enjoy the work I'm doing anymore. In fact, I don't really enjoy playing hockey that much these days. That's pretty stupid, since it is recreation, and fun is half the point of it. Yes, the exercise is valuable, but I have many options for getting exercise, such as going to the gym, lifting weights in the garage, biking when the weather allows, etc.
I have many thoughts about the work situation. Mainly, right now, I'm happy to have work at all. I went the first half of the year getting about 10 hours/week in on good weeks. So, I'm not in a hurry to jettison the thing I have. But there is no reason not to really think about what I want to do when I grow up, because before you know it, I'll be 50.
