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.
