Hey Dave! Great to see you here in the LB&L Forum from the FB group!
One thing you can always be sure of....cat's hate to be predictable! So of course on the morning of your first shot of Lantus, you get your lowest number ever!!
It would actually be helpful if you could go back and add maybe a week's worth of test results from when you were using the Vetsulin on your spreadsheet. Then you can add a line in between to show you've started Lantus. (if you look at
4/1 or 5/18 on China's spreadsheet there's an example)
Apollo is stunningly beautiful!! How much does he weigh?
If I'd been able to be here earlier, I would have suggested you go ahead and shoot as long as you had plenty of supplies (strips, medium and high carb food, Karo/honey/syrup and the ability to test as often as necessary today)
Next time you get a PS you're not sure about shooting, you can Stall,
don't feed and test again in 20-30 minutes to see if the number goes up without the influence of food. If it does, that's usually a pretty good indication that the last shot is starting to wear off.
The thing to remember about Lantus is you're not really shooting the number he's at now....the dose doesn't usually start to "kick in" for 2-3 hours, so it's like you're actually shooting that number (you'll also be feeding him which should bring the number up too)
We usually suggest that if the cat is above 150, you should go ahead and shoot the scheduled dose. Get a +1 and +2 when you're shooting a lower PS number so if you do need to intervene, you can do it early. As you gain more experience and data, that 150 starts to come down until you're willing to shoot anything over 50. "Shoot low to stay low" is a common saying you'll hear around here!
Since you were on 2U of Vetsulin, you could start at 2U of Lantus, but if that concerns you, there's nothing wrong with starting a little lower, like 1.5
Keep asking questions! No question is a dumb one here!
