Thanks for the replies
@Wendy&Neko and
@Hroswitha ,
I got behind on messages due to a stomach bug

but am back.
I took the slower route and increased her to 4.25 this week, but she's still high yet flat-ish.
I should've framed my question better: I'm hoping that the flatter curve and signs of her finally hitting the 200's is a good thing and hopeful that we are getting somewhere.
I am trying to get some night readings when I can, but I do need sleep. So I do what I can (I got a late-night nadir recently, and as I suspected, it was in the same range as the daytime)
I am suspecting IBS because of stool and food sensitivity problems that she has been having for quite a while.
I recently removed fish from her diet, about a week before we started getting more yellows.
For instance, she was doing good while I was feeding her Pure Vita chicken, but got semi loose stools today after I introduced some beef last night.
Today her curve looked like the insulin was non-existent. (350-407)
Could be fur shot, but I felt the needle go in and double checked.
I get that more testing is better, and I plan on doing more preshot tests when she finally starts to go down.
Right now, I can't quite afford to keep buying test strips and have to be more judicious with my testing. (But I have some help coming soon from DCIN and PRAISE BAST FOR THEM!)
Plus, she is not the most compliant cat and I already have to pill her once a day. Her quality of life is very important to me. Right before a meal is the hardest to get a read since she's all excited and antsy.
She is also a HCM/CHF kitty, and that is the most important piece. Too much stress can cause her respirations to go up... so it is all a balancing act I am learning.
I will pay attention to headings next time, but it is possible that this particular forum is not right for me.
Thank you bot for the replies!
