1st day of infusion site routinely being awful.

Question

Does anyone else have an issue with the fists day on a new infusion site? I've used autosoft 90, trusteel with the tslim and mio advanced with the 780g and all three of them I routinely have my ratios being out of wack.

I eat the same thing every day for breakfast, and on the first day of a new infusion site I have to double my usual dosages for breakfast, lunch and afternoon snacks. By the time of dinner it's coming back into the range it should be. The last 2 days of a site always run normally.

My endo and nurses all insist this is just morning phenomenon, or feet on the floor syndrome. (I find I odd they had two different ailments for the same problems). But at this point I've got about 35 pages of printouts showing my sugars over the 3 day site rotations, and each and every one shows either significantly more insulin needed to stay in range or my sugar spikes way up to 13-16 before I rage bolus to get everything back down in range.

I've tried different locations with the same effect. I've tried soaking a site for an extra day before usage with mixed to the same results.

Anyone else have this issue? How do you deal with it?
