I mentally prepared by thinking, "Now here's what you do Sarah, just press the stop sensor button, then press the start sensor button. That won't be hard, will it?" Then I did just that. I had an ominous feeling about the whole thing, but I ignored it. I figured that if a bazillion other people did it, so can I. Well, I was wrong.
I also had to grab an extra pump site because I needed to change and I thought I would change it between that 6:05- 6:44 range. Obviously that didn't happen. I changed my site in the car on the way to school, so I could only put it on my stomach about an inch away from where it was before. My CGM was also on the other side of my stomach, so my site and sensor kept bumping into the sides of tables. (I'm short, okay...)
Briefly, my sensor thought I was 324, so I went inside to check my blood sugar, and it was 199. I quickly put my blood sugar in and the sensor has been working ever since.
Moral of the Story: I should really stick to the FDA's guidelines.
