Mishu was diagnosed 2 days ago, he is 8 years old. We are using Lantus, 2ui 1 shot per day, for now i go to the vet for the shot because i don't know how to do it myself. We are not home testing yet, i am still looking for a tester. Is it nornal for him to be very sleepy? He eats, drinks some water and then back to bed. His ears are cold, his nose is wet, he reacts to sound and last night played a bit with me. Today is our 3rd day, we are going back to the vet in 30 mins, i'm just really worried, our vet said that it may take a while for him to adjust to the insulin.
