Yesterday Well, I opened a new pen yesterday, and at first I didn't think it was having any effect, but now I'm not so sure. I will keep using this new pen for the next several days and see if his numbers are lower. If they stay low, I will probably try the older pen again to see if anything changes. I don't want to waste a perfectly good pen, if I don't have to! Squallie has been pretty full of himself this morning. I don't think he is comfortable when his BG goes up, even tho' he isn't really in high numbers; he seems much happier and more active when it is lower.
