Has anyone else noticed a loss of effectiveness on the 3rd day of using a cartridge/wearing an infusion set. For me, on the 3rd day, I wake up high, bolus, and it seems to have little effect. The only days I see in the 300's are on the third day.
I've only just started to notice this, so I wonder if it's the heat of the summer that's degrading the insulin in the cartridge. Seems like other people should be experiencing this as well though.
