So I am still switching over to Lantus. HOWEVER, my soon to be EX vet is being very difficult with a Rx for Lantus. The PLAN was to switch to Lantus by the end of Prozinc, but it's taking longer and I may have to purchase another bottle of Prozinc just for 2 weeks (if that). :/ That being said, I'm at the end of the bottle, it's time is up and it's not as effective as it once was. My numbers were too high and I've have increased to 2 u. My question, if I have to start the new bottle before the vet gets their finger out of their butt, what should I start on? I feel 2 units of a fresh bottle will be too much. I looked back, and I was thinking I should start on 1.25. Curious, how the more experienced in the matter suggest. Can I drop it back that much (from 2u to 1.25u) or is that too drastic? My vet appointment is Weds morning.
