I changed my set and reservoir this morning. Managed to trash both a set and reservoir before I got it right. Pulled the plunger clear out of the reservoir during the initial 2 pump set up. Then I accidentally pulled on the set tubing a little too hard and pulled the whole sucker off of the needle/Inset inserter.
Also, I've been throwing away around 50-80 units of unused insulin with each set change.
The tweaking and learning is fun, but it's getting pretty wasteful. For a poor conservationist, this has to change...
