Keep Dropping Inches

Yesterday I worked form 7:00 - 6:15 so I was really tired when I got home and haven't made the best choices over the past couple days. Okay, I don't understand this - I keep dropping inches but my weight keeps fluctuating between a couple of pounds. Weird! So, there's the update for now - I think part of it's just the stress - although good for changing jobs... Possibly of not getting enough sleep either.
