In my last post, I talked about the possibility of maybe filling one of my pump’s insulin cartridges and simply changing my site mid-use. Doing this would save how much insulin I waste both in tubing and in that “cushion” of insulin that Tandem’s t:slim pump has since I’d only be throwing those out every 6 days verses every 3.
So, I started my experiment last week. I filled my cartridge up, hooked up, and hoped for the best.
After 3 days, I got the alert to change my site. By this time, I was down to 155u, so I was right on track for the mid-6 day site change-out.
Now, last night was the time when I get nervous because a) it was night time and b) I had 18u of insulin left. Looking at my pump though, I used only .9u per hour during the night, so I would have had enough to get through until morning. So, I got my little change-out bag together with my site, tubing, cartridge and filled the syringe and had it all ready to go.
I got to work and after bolusing for breakfast, my pump was down to 2u. By 10am, I looked and it said “1u”, but I knew it would alarm empty soon…
And then it did…
So. After 6.5 days, I was ready to change out again. Best part was, I didn’t have any decrease in glucose control throughout the whole process. Granted, once warmer days get here, I may need to go back to changing everything out every 3 days, but at least during the cooler months I know I can do this as an option.

Now, on to find an angled site I can use higher on my belly or on my love-handle area since this growing little baby is now starting to use my mid-section for a temporary home. 🙂
