Thanks for the kind responses, everyone!
So, yesterday I realized I had been completely soda free for a week. I remember I posted something about getting through the weekend without having one. I think I'm going to keep doing that until I slip and get one. Right now I'm working on week 2. I'll be interested to see how long I can go. I almost got one at work (damn vending machines), but stopped at the last moment. I literally had my money in my hand and was standing in front of it. Then I thought, "I don't need this. It isn't worth it. Just walk back to your desk."
Did pilates today! It was rough because I did pilates yesterday too. My abs are going to be so sore over the next couple of days. I have tomorrow off of work, if not class, and I think I'm going to try to do an hour yoga, a 1 mile hike, and an hour of zumba. I've never tried to do that much in a day before, but I think I can handle it at this point.
I'm really nervous about weighing in this weekend. Last week I gained and the week before that I stayed the same. I really want to see down this week.
