Hey Gretchen! I'm in PDX too!

I use the Daily Plate to track my food because I've got a Gowear Fit, the non-food-tracking cousin of the BB, and also because I really like the way TDP works, it's very fast for me to just hop on there and find whatever it was I ate.
And UK, I know, I'm the same way!! I actually had a -.2 loss my first week with the armband, and I'm convinced it was due to water retention from all the new exercise I was doing. The next two weeks I lost 6 pounds, though, because I've been drinking about 2 liters of water a day, plus keeping an eye on my sodium intake in the few days before my weigh-in. Seems to be doing the trick!

Honestly, since getting the armband, I hardly think about food and exercise anymore.... now all I worry about is water retention!
