Awww, thanks you guys.

I knew I could count on you to make me feel better. I guess what's scary to me (besides her increased numbers, of course) is just not knowing how long she's going to have to be in them. I mean, if her correct dose is 3u, just to pick a number out of a hat, then it's going to be an awfully long time until she reaches that dose.
To answer Gayle's question, the vet did a urinalysis (done by cystocentesis) to check for any UTI-type infections, and I also had her do bloodwork on Buzz to rule out anything else that might be going on. The u/a was negative for everything (except glucose, of course

) and the BW showed no infection either. Buzz's BUN and creatinine were elevated. I've gotten advice here (and from the vet) regarding that and I am going to recheck again when her BG has been stabilized for a month or so.
I understand from the board that tooth problems may not show up in BW, but I was told that it's hard to get a good look at the teeth without sedation. I really, really can't afford another vet bill right now, therefore that is going to have to wait. If her #s don't come down with increased insulin, I will have to look into it further.
Libby, that's good to know about the "not usually a gradual change" on Lantus. I was really worrying about that, thinking that maybe Buzz was one of the freaky ones for whom Lantus doesn't work, so thanks for that info.
Thank you for all your words of encouragement and hope. I really needed them today.
ETA: Heather, no kibble around. The dog food (only dry food in the house) is now sealed up and put away. I hide/put away human food obsessively, so I am 100% sure that there is nothing she can be getting into.
