A housekeeping note: We link the previous day's thread to the current day. It makes it easy to backtrack for information vs searching the entire board. Here's
Buddy's thread from yesterday.
Given that Buddy has been in high numbers, I would strongly urge you to get some Ketostix. The basic "recipe" for ketones is not enough insulin + not enough calories + an infection/inflammation. You shot a reduced dose, his appetite is off, and it sounds like there may be something GI going on plus it sounds like he's lethargic. I'd get a ketone test.
If the ketones are trace or under, I'd see about a vet appointment -- or if a vet is open, get him in even if it's precautionary.
As an aside, I think you're holding Buddy's doses for too long. It doesn't look like you've decided which dosing method you want to use. Even with the less aggressive approach, Start Low Go Slow, you hold the dose for a week, do a curve, and if needed, increase. You've been at the 3.0u dose for 2 weeks. In addition, I'd encourage you to get some spot checks during both the AM and PM cycles (and definitely a before bed test every night). Lantus dosing is based on the nadir -- the lowest number in the cycle. You have very limited data so it makes dosing decisions difficult if not impossible. With no PM tests, you're missing half of your data.
