Satin is 13 yrs old now and has been diabetic for 10 of them years, so I have been at this for a while. She has been on the BCP PZI for about a year now and about two weeks after I started it is when the vomiting started. I do home test and her BG's are always up and down, but they always have been, but lateley she hasn't been eating much as I think she is upset to her stomach so they have been lower and I have had to lower her dose. I use BCP PZI U40. She just had her yearly checkup about 6 months ago and the vet said she was doing good but had no answers for the vomiting. She vomits about once a week and it's usually what she ate last, but after she pukes all that up it's just saliva that comes up. Satin eats dry Evo and can food. I had her on Lantus for a while but she did terrible on it and got keytones as a result from it, so I do not want to go back to it. Thank you for your comments!
