Good compromise!!
So, for tonight, barring anything out of the ordinary, the plan is to shoot the same, 1.5u dose.
I'm going to do a bit of explaining so if you're tired of hearing this stuff, PM me and tell me to shut up. At this stage, you are working on building up a blood level of Lantus in Sasha's system. (This is also referred to as a depot or, in these parts, a "shed.") Many long-acting drugs work on this same sort of principle. Part of getting the shed established is giving a consistent amount of insulin since the shed is being built around whatever that amount of insulin is. One way to think about this is you have 1.5 units of insulin in storage. If and when you need to increase a dose of insulin, it will take a day or two to fill the shed. When you need to decrease the dose, it can take a cycle (12 hrs is a cycle) or two to deplete the shed to your new dose. This concept of the storage "shed" is one of the reasons that a consistent dose at AM and PM is important, especially as you're starting out with Lantus. It's also one of the reasons that small changes in dose work better.
When you have some spare time, there are two things that will help everyone here enormously. The first is your spreadsheet. This will help us and you keep track of Sasha's progress. It's also something you can send your vet so he can see how Sasha is doing. The instructions for the
spreadsheet and how to link it to your signature are in the Tech forum. Also in the Tech forum are instructions on how to complete and link a
profile. The profile will save us from repeatedly asking you about Sasha's diet, date of diagnosis, health history, etc. The spreadsheet is the more important of the two items.
