Congratulations, that's really fabulous news. I bet that you're feeling a lot better for being rid of the infections and having better glucose control - both bring you down and can make you feel grotty without you necessarily being able to put your finger on why or how. You just know you feel better once they're sorted.
It certainly is frustrating, my BG has been all over the place for the last 6 weeks and whilst improving with my new insulin regimen, I'm not quite there yet. I look forward to the day, hopefully soon, when my BGs will be equally good again.
