Hopefully you have been able to handle Quincy's ears getting him used to the testing process, because when you are injecting the insulin it's very important to test before every injection to be sure the BG is high enough. Then you will test as you can during the 12 hours between shots, to see how the insulin is working and to see how low the BG goes. Basaglar is dosed based on the lowest number in the cycles, not pre-shot numbers. The spreadsheet is going to be invaluable to you to record and track the data. I am so glad to see this type of insulin, it works well for many of our sugar kitties.
To be honest, not every day or even every cycle may go smoothly. You may have
temporary bumps in the road with not being able to get Quincy to let you test (it takes lots of patience and practice for some of us), and you will learn what technique works for you when you do the insulin injections. But, you are already very proactive with the diet, getting your testing supplies and setting up the spreadsheet.
It actually does become routine, and the more you go through the processes, and the more you educate yourself the better off you and Quincy are going to be. Read the stickies at the top of the Lantus/Basaglar forum
HERE. That is the forum where you will ask questions about using the insulin and dosing. It's a very supportive forum and I think you will enjoy meeting the fellow glargine users there.
They are very data driven and before offering advice or input, they are going to need to see testing data on the spreadsheet. So, the sooner you begin that, the better. Do you have any idea what dose of the Basaglar the vet wants to start Quincy on? Just a caution, many vets start out with a higher dose than we suggest, basing dose on the few or the one test they have obtained there. If you can start testing more often before you go for injection lessons, that might help them determine a good dose to begin with and hopefully not be too high at the get-go.
Here's the basic testing routine we recommend: (do what you can on work days - before bed is useful along with the essential pre shots)
Test every day AM and PM before feeding and injecting (no food at least 2 hours before) to see if the planned dose is safe
Test at least once near mid cycle or at bedtime daily to see how low the BG goes
Do extra tests on days off to fill in the response picture
If indicated by consistently high numbers on your spreadsheet, increase the dose by no more than 0.25 u at a time so you don't accidentally go right past a good dose
Post on the insulin support group forum (L/B/L forum) for advice whenever you're confused or unsure of what to do.
Even though you are not injecting yet, you still could begin the routine and get some data to provide to the vet so Quince doesn't start out on a higher dose than he actually needs, especially since you have transitioned to the low carb diet.
I think you are going to be just fine, it's just a new learning process and you have been down that road many times before.
