Okay - good. I always hate to jump in and raise questions/offer advice when people don't really know who I am, why I'm here, or where I came from!
I go with my gut too, so not challenging - or judging - just seeking info.
Robin was always the queen of the sliding scale. I hesitate to suggest one, since I always shot pretty consistently, but I get the concept - I tried using a sliding scale with R insulin, but G's resistance was powerful and he didn't move for a normal dose of it. I had PZI friends here who shot 10/14 instead of 12/12 (due to work schedules), some that shot 12/12 with higher/lower doses for the am/pm, and then those that used the sliding scale. Guess I was the boring one! ;-)
My only concern with a sliding scale is if you're shooting a bounce. G barely moved, so I didn't see many bounces (we called it "hanging out at IHOP" as he was usually flat as a pancake!). The rule of thumb is to NOT shoot bounces, so I don't know how you tell the difference between a bounce and a normal high. That's why my feeling is for the consistent dosing. But you've got to use what works for you, especially schedule-wise. I went from shooting at 6:30 am/pm to 10:00 am/pm so I could be home/awake when he nadired.
Snacks can be your friend, as well as (like human diabetics) multiple mini-meals. I bought Grayson a PetSafe 5 auto feeder ($49 Petco on line - price matched at our local Petsmart - saved $15). Now I wouldn't be without it! I program the feeder, and have it set to rotate at both AM and PM +2, +4, +6 and +8. He gets 1/4 can FF at each of these times. This has eliminated the food spikes I was seeing - as much as 50 points/can at a time when G was eating 2 FF cans at shot time (Acromegaly made him ravenous!)
I'll look forward to seeing your numbers when you post. My only wisdom is to check your previous numbers and see how he responded when you are deciding what to shoot.
Hope he gives you some nice numbers! Good night!
