ok, so I looked at your SS and I am going to give you some advice
You have been at this for 4 months now, with no really good numbers consisstently
It seems that you have gone up and done for those 4 months with no progress
SO..I am going to suggest that you should not lower for now..
you should start working your way up..maybe start with 1.5 hold for 4 days
then raise to say 1.8 hold for 4 days, raise to 2 hold for 4 or 5 days...
You really should try something different instead of going up and down
keep the dose steady but keep climbing...
so many kitties need 2.5 3, or even 4 units twice a day....
Look at shakes, in the beginning I did the same thing as you, I kept going back down because
I saw some good numbers when he was lower but they never panned out,
so now we are at 3.2 units 2times a day and he is doing pretty good...
SO if you want see what everyone else says...but I think you need to start steadily raising
just my thought!
