You're not the only one. It's so easy to start the day with good intentions and then, with one situation or another cropping up, or just having a hectic life in general, the good intentions just fall by the wayside. But you have made a great start, losing almost 30 pounds already!
I love your idea of "saving for the new wardrobe" - that's a really good idea!
I might have to convince DH to let me give that a try.
