Your SS is working wonderfully! And good job getting tests in.
I went back to your initial (long) condo/thread on Health. When you have a chance, can you complete a
Profile? This will consolidate a lot of information so we don't keep bugging you for things like: when Little Boy was diagnosed, any health conditions, what you're feeding, etc. All of this is important for us to know in order to have the big picture.
For a newly diagnosed cat, the
Tight Regulation Protocol suggests that starting dose is based on a cat's ideal weight.
Tight Regulation Protocol said:
In many cases, the starting dose of Lantus or Levemir has been 0.25 IU per kg of the cat's ideal weight and is always dosed BID (two times a day, 12 hours apart). If the cat received another kind of insulin previously, the starting dose should be raised or lowered by taking this information into account.
For a starting dose of 3u, Little Boy would need to weigh 12 kg (almost 26.5 lbs). Somehow, I don't think Little Boy is
that big. What is his ideal weight? And, would you be open to reducing his dose?
One of the issues with starting with a high dose, and this is a high starting dose, is that you don't know if you've missed what may be an optimal dose for your cat.
Also, I really want to caution you about not getting a pre-shot test before your evening shot. While Lantus dosing is based on the lowest point of the cycle, shooting blind is dangerous. You have no idea where you're starting and whether it's safe to give a shot. My cat, Gabby, is notorious for quick drops. Without knowing where you're starting, you could end up with a +1 that is very low. Please, please, please do not shoot blind. It is a terrible habit to get into. You also need to get at least one spot check per cycle. More is better but one is good.
I also saw your note in Health about injecting air into a vial. There is more of an issue with injecting air back into the cartridges or pens. It's not something you want to do with a vial, but the concern is less since the insulin in the vial is not in a pressurized form. You don't want to get into the habit of injecting air. You will find that buying the pens or cartridges will end up costing less and being more economical with respect to waste. The manufacturer recommends that once opened, Lantus' shelf-life is 28 days. Many people here get a longer use from their insulin. Many of us don't. As a result, there is much less to discard in a pen or cartridge than in a vial.
