Good luck with the re-start KB. It's great that you're so motivated despite the time of year! As I've said lots of times before - we only fail when we give up, and you've never given up. I really do believe that you will get there. I never thought that I would, but it must've just been my 'time' last year - there was no magical lightbulb moment, it just seemed like any of my other new starts, but I guess I just got into the right groove this time.
I did consider getting a fitbit myself actually (or asking Santa for one) - but I don't think it's such a good idea for me as I can get a bit OCD about calories consumed/calories burned at the moment. I do have a pedometer that I've recently started to wear again though. AND I've just acquired a treadmill via Freecycle, so hopefully 2014 will see a much fitter me!
Hope the GP is open to the idea of the Xen...I still have a 'comfort blanket' supply upstairs, lol!
