I have 3 years experience with and acro cat, PZI and a sliding scale...but it was LONG ago. Started Crackerton on lantus...he is on such micro doses the shed is majorly screwing him up. .25 unit is too much once the shed is full and 1 drop is not enough. He had major dental issues that now fixed may be having him close to remission. He has horrible neuropathy. I am starting a dose of .2 unit by using a u100 syringe. I will eventually need help with a sliding scale...so happy to be rid of the shed! Any advice appreciated....the bouncing happened every time his shed got full...poor guy.
