Hi there,
I don't see enough information, as Deb said, about Sam on his spread sheet. You seem to have been missing some other days also?
What caused him to drop into the 20's on March 25th? Do you know?
I had treated one of my diabetics with Lantus, but I know that I was usually more or less afraid to go changing the dosing around at times, and I don't know if you have had Sam on the Lantus long enough for a change that high. Doesn't seem high, but I think with Lantus, it does, especially if you are going to up it with both shots during the day?
Larry has a lot of experience with Lantus, so I would think he pretty much knows what is okay to do.
I usually used PZI, and I only had my cat on Lantus for about a half of a year or so. Both of my diabetics are passed away now, though.
As Deb recommended, best to get as much info on your signature area if possible, and try not to skip days on the SS. Do you keep a little notebook with you when you shoot the insulin? That way, until you get back to the SS, you won't forget the test numbers or the times, etc.
Good luck!
