When I am losing weight I get this pain. I cannot describe it but it feels like a kick in the ribs. It normally makes me feel good that I am losing, but it can be uncomfortable.
Anyway, it's 4am and I am at the airport and this pain is pretty intense. Normally, I would not notice it at this time because I'd be asleep.
So it looks like when I snooze, I lose. Which is good. Because I don't like feeling like I have been kicked this hard in the ribs!
