I find that I have insulin resistance that is of a mental/emotional nature, too.
That is, sometimes I just can't
inject enough insulin to cover my food.
This usually happens when I over-eat and the calculation on my carbs/insulin kind of floors me. I still binge from time to time, and when I calculate and discover that I need to inject 80 or 90 IU to cover the binge I just...can't do it. I'll inject 45 or 50 instead, scattered around in three or four injection sites (twelve here, fifteen there, etc.)
I'll inject half of what I should and tell myself, "I'll test later and correct."
As I'm a T2 and still make some insulin despite being on MDI of Lantus and Novolog, I can "get away" with a bit of this. That is, if I've been walking daily, eating fairly well and regularly doing my basal/bolus, then if I have a rare binge and fail to cover it all, my sugars will go up to 280 -- not 480 -- as my body kicks some in to help cover and my insulin resistance doesn't fight me as hard.
However, if I go back to my bad old ways and do this nonsense more frequently, the base-line will creep up and up over a period of days and it will take me a week of perfect vigilance to get leveled-off back at a good place again.
I wish I could just STOP this nonsense, but if I put on my scientific observer hat I think it's fascinating that I'm sitting here with the Novolog pen in my hand and the cold, hard facts of my carb consumption right in front of me and I can't inject what I should
. I just...balk. I've no idea why. It's like a mental block or temporary insanity that goes with the mentality of binging. It's almost as if injecting what I should makes the binge more "real"...or something like that.
Human beings can be weird, and I'm no exception...sigh...
Do you ever resist injecting the right amount of insulin for mysterious emotional reasons
