Hi, Melissa, been reading your posts because I am in the very same situation. My cat Alley was doing very well with all the help from this site, then, an infection has blown it all away. We have hit 500 yesterday AM and am going crazy and feel helpless like you do. I have increased too soon I am sure but the high numbers have made me trigger happy. What a disaster! I believe I will decrease back to .2 probably tomorrow. Can't go much higher on the dosage because I believe in my heart that Alley belongs in the .15 to .20 range. He is on Clavamox until next Friday also, then he needs a dental for a bad tooth. He also has an ear problem with a slight infection, but that medication is all done and he seems better there.
Hang in there, please don't feel it is hopeless, we all get there from time to time.
It has to be the infections our kitties have, along with some discomfort they feel that is stressing them out.
We can both do this, Melissa, the Lev is the best insulin and the people helping here are the best, we will succeed.
Good luck
Pam & Alley
