Hoping the dosecrease goes well!
I'm also starting to suspect that maybe the insulin isn't good anymore - back when I was a new sugar kitty mama I don't think I handled the pen and drawing doses totally correctly (air bubbles, etc), so maybe that's affecting the efficacy? Either way, I've ordered some insulin from Marks for the first time, hopefully it'll be here in a week or week and a half, so I'll open a new pen.
