Hi again Linnea!
Do NOT give any more insulin tonight! Figure out a time that will work for you so you can give it every 12 hours. The same dose, every 12 hours (give or take no more than 15 minutes)
You don't give more insulin just because Char is hungry. He'll be hungrier than normal until he's better regulated. Just feed him like you always have, but take any food up 2 hours before shot time once you're testing. Since you're not testing yet, you can leave food down
In the morning, when you decide on a time you can give shots 12 hours apart, give him 1 unit. That's a fairly safe dose, although without you home testing yet, we can't know what dose is best for Char.
I might even only give him .5 to start with since you're not home testing yet. I will get one of the more experienced members to check in and give you her opinion
It's REALLY important that you start home testing. I was hoping you'd been able to do that a little during this last week while you were changing to low carb foods, but understand that your life has been pretty crazy.
Once you start giving the Lantus 12 hours apart, you want to HOLD the same dose for at least 6-10 cycles, so if you're giving 1 unit, make sure you stay with 1 unit, no more, no less.
I can't find a picture of 1 unit, but if you look at this picture, this is .25 .... 1 unit would be the 2nd line (the first line closest to the needle is 0..the little line in between is .50 and the next line is 1 unit
PLEASE start testing as soon as possible. The last thing we want is for you to have a hypo situation that could cost you Char's life...or 1000's of dollars in vet bills!!
