Hang in there... believe me, I'm the queen of impatience, so I have to sometimes repeat out loud "marathon, not a sprint.... marathon, not a sprint..... marathon....."
I'm guessing that wild swings in BG #s aren't the most wonderful thing in the world for anyone... furry or otherwise! And at first, low numbers will feel weird as well. But Checkers will get used to things, and will start to feel better. Willie had other things going on when he was diagnosed, so he was pretty miserable. Once we got that fully under control and he got used to having lower numbers, his mood improved dramatically! He's 15, but now spends much of the day in spontaneous play (granted, followed up with lengthy naps... he's sleeping on my feet as I type!) and is just a happy, furry purry guy. His fur is now shiny and glossy and he has more energy than I could ever imagine him having, and this is just 3 months from diagnosis!
The important thing to remember is that Checkers is now on a solid path to better health, and that is because of you. You are doing a great job!!
