I switched to Prozinc a week ago and Ducote is getting much better numbers but I am in new and scary territory. I am trying to absorb as much as I can so that I know what to do when he dips down lower than expected. He started Prozinc at 3.5u and on his second day he earned a reduction so now he is at 3.25. This morning I tested him and it was lower than I am used to (124) so he ate and I held the dose for an hour. His recheck was 165. I did not give him a full dose but did give him 3 units. I just checked him again (+4) and he is at 56 ! He is currently chowing down on a can of Fancy Feast trout and I will recheck him in about an hour. My question is: I know that a reading under 90 equals a dose reduction but this morning I gave him a reduced dose of 3 instead of the normal 3.25 due to the low number. Do I reduce from the number I gave this morning that brought him so low or from the normal dose he is at for now (would his new dose be 3 or 2.75)?
