I was trying to find my old post to update it, but just figured out the board updated software and it looks like old posts were lost. Anyway, this board helped me regulate my 14yo DSH after he was diagnosed with diabetes. We were using Vetsulin and he did so well, we were able to take him off insulin completely after 4 months. Unfortunately he's had a relapse and the Vetsulin isn't lasting the 12 hours. I'm working up a curve on him now to see if it makes sense to dose more often or possibly switch. However after spending the past hour reading, it appears ProZinc is no longer what it used to be (and expensive) and Lantus even more expensive. Any recommended threads on pricing and best places to buy?
