I've been doing a few BG blood tests every day on Quincy... ( doesn't phase him a bit! ) He's currently on 2 units NPH 2 x day.
I've found he is at LOWEST at the end of the 12 hour period! Seems to be highest at abot 5-6 hour! Just the OPPOSITE of what should be the 'norm" where insulin brings BG down about mid-way of 12 hour period!
Now Missy peaked early ( went lowest at about 3-4 hours after food and insulin) and I was able to adjust to that by giving small food snack just before her peaking) and it worked out fine. What to do about this "lowest" at injection time befuddles me. I have chemo this AM so will have to do my 'researching' later.
