Glucose Reader trouble & new insulin

Well.. we were doing pretty good with our reader till about a month ago or so.  Suddenly we kept getting an error message ER 6 and had to use multiple test strips until finally the reader took a reading. We tried a new battery.. we tried everything to fix it. The vet ended up allowing us to borrow one of theirs for the last curve we did.  We use One Touch Ultra (the first series I think) and it has a life time warranty.  So we did call the company... who I might add was very friendly and sent us a brand new one with new test strips for free. We didn't even have to send the old one back to them! (the picture is the Ultra2 not the one we have but I am too lazy to take a picture of the one we have right now.. ha!)

The vet has changed Merry's insulin. The name of it starts with a B and I am posted this post after we tried it so I don't remember the name. It didn't work on him at all.    The litterbox is like concrete and he is drinking a lot. He switched from Prozinc.  Now he is back on the Prozine and Glipizide pills.  I am not really sure why the vet changed him because he was having good numbers?  I think she was trying to make it cheaper for us but in the end now we are just starting all over and building him back up to 8 units of insulin. Pippin is doing fine but he does get constipation a lot since he's been on the diabetic food. We started him on some stool softeners today to see if that will help.  When he gets constipated he pukes and stops eating.  Till the next update!
