Yea I have been following your posts each day and rooting for Sam to find his sweet spot.
One positive aspect for Chronos is that he has yet to display the symptoms of diabetes, no increase in drinking, we've always added water to his food for kidney stuff, so he doesn't drinking normally, nor increase in peeing and his weight is good, actually been going up I think because of the insulin so might have to cut some food since he is already a little over 18lbs.
That was actually how we found out his BG was high back in April, seeing him drink, some weight loss and then I checked his BG (we had our monitor from another cat and saw the 300s). Guessing back then he probably had been in the range for awhile and then got to the point of showing symptoms. But this time since we were checking his BG every few days we probably caught it as he was coming out of remission from the diet change but before his body started to show symptoms.
Will see what his +5 is then give him a break from pricking til PM shot, did quite a bit yesterday, feel bad for his ears.
