What the what. So here's my initial thread with background: http://www.felinediabetes.com/FDMB/threads/newbie-here-330-bg-amount-insulin-to-give.169449/ This morning his AM BG was 340. Last night was 284. He got fed immediately afterward. About an hour after he ate (he actually ate twice during that time period, he's a bit of a grazer, though he wolfs when he eats), I gave him his very first shot of NPH (Novalin N), which is what the vet gave me, 1U. Took me that long to do it since it was my first insulin injection and I checked out a few videos again to be sure I did it right. I also double-checked the syringes, yes, they are U-100s. Although he was diagnosed on Friday as being diabetic, I waited until today to do the first injection since I didn't want to do it over the weekend just in case (hard to get hold of vet on the weekend where I live), plus today I'd be home all day to monitor. Just now checked his BG +2 and they show 40? Holy moly, that's a big drop. Am using Bayer Contour Next. As soon as I saw that reading I opened a new can for him (FF chicken classic, it's everyone's fave), which he happily set to. He's now curled up beside me, purring away. Does not seem to be in any lethargic state, is behaving perfectly normally. Might my meter be wrong? Should I test him again right now? I planned on doing a curve today since I'll be home all day. I didn't expect such a drop right away, though. Good thing I didn't do the 2U the vet originally told me to do!
