Wow, this discussion is wonderful!
Wow, my head hurts!
I didn't try the alternating dosing as the vet suggested last Wednesday afternoon because frankly I was afraid of messing up what I'd achieved with him.
But, I do not feel comfortable working against her recommendations, as I respect her, so it feels wrong.
She is worried I am going to end up calling the clinic with him in a hypo emergency.
(I'm not sure she appreciates how hard I've been trying to avoid the same thing!)
She felt strongly that I should try it, knowing I could go back to regular dosing if it didn't work out.
But given his better results today, I think I will continue on the 0.10, maybe lean towards a 0.15 like Wendy has suggested, but regardless, stick to a minimal amount of insulin on a daily basis for now.
I have to report back to her next week.
His blood sugars seem to follow a pattern until they don't.
I am simply encouraged that overall, his trend for blood sugar levels has been going in the right direction - that is, downwards.
Toeby is not in the best of health overall...
He lost quite a bit of weight in the last year, while his brother got fluffier (like I did - I can blame Covid

).
I certainly don't fool myself that he is going to live to be 25, but I do want him to at least feel okay while he's here.
Today he certainly seemed to feel pretty good... even got his old crappy attitude back, beating up his brother like he used to when he outweighed him.
Now, I have to re-read all this discussion and make some notes for myself.
Thank you very much, everyone!!!
I appreciate the input.
