I hate to blame the pump but can't find any other likely targets, so I will be taking a break for a couple days. The timing is not ideal with Wildflower on Saturday, but I am very frustrated. I did a basal rate check this morning--no food, exercise or bolusing from last night around 8:30 PM until noon today--and everything checked out perfectly. After midnight, it was more or less a flat line, trending ever so slightly downward. But after a lunch and snack later on, using pretty much the same bolus I would normally take, my blood sugar spiked to 410 and has been very slow in coming down even with my rage bolus on board. This has been the pattern I had been experiencing in the morning and it seems to have just shifted to my first bolus of the day. Any boluses I take seem to have a 3-hour delay, like I've got some nasty Regular-NPH combo going in. (I'm on my 3rd vial of Humalog and the vial I sent back to Lilly checked out okay.) I called the customer service at Animas and they were helpful; it doesn't seem like the pump is malfunctioning in any obvious way. But I just have this feeling that I get better insulin delivery through a needle. You know what I mean? Maybe being on a pump since 1993 has created too much scar tissue. But so suddenly?? I was doing just fine until 3 weeks ago.
So I'm done with the pump for a couple days. We'll see how it goes. I need one of those insulin pens.
