We totally get that. My vet didn't give me a whole lot of info either. A bit more than yours did, but not much. I found this forum first thing (luckily) and got my info from here!
To give you some basics: I see you are use the AlphaTrak. Most folks here us a human meter (the strips are way cheaper) but the AT is fine too. Basically, on that meter, below about 68 is where we consider the cat to be going hypo. So I would probably set about 90 or so as the point to start watching very carefully. Basically that just means if you get a 90, keep an eye on things to see if she is going to continue down.
In the morning and evening, we test, feed, and shoot all in about 15 minutes. We do it like that so there is some food onboard to help when the insulin goes in. If you get a test that is below...I believe 220 for an AT meter, you want to stall WITHOUT FEEDING for 15 minutes or so. Then retest to see if he's come up to a safe shot. We consider 220 to be the cutoff point for shots for new folks. Some of us shoot under that number, but we have data for how our cat reacts. If you get that number and he doesn't come up preshot, it's best to skip. That way, you don't worry about a hypo.
Generally, we consider a cat well regulated if they have yellow preshots and double digit midcycle points (what we call the nadir) that is lower than 68. Since you have just gotten this diagnosis, though, it might be a bit before you reach that point. Don't get frustrated if you have higher numbers at first. that's pretty normal at first.
Do you have a hypo kit at home? Karo syrup or high carb food? If you get a low number (or are approaching one) post here. There's usually someone around on Health even at night and we've walked plenty of people through hypos. They can often be handled at home...and people aren't afraid to tell you if they feel you need to head to a vet.
Okay that's a lot of info all at once. I don't want to overwhelm you more than you already are I imagine. The last piece of info for tonight. We have a protocol for ProZinc we put together. It's here:
http://www.felinediabetes.com/FDMB/threads/protocol-for-prozinc-pzi.109077/ . I'd read it when you have a chance. It can help explain how we dose.
I'm about to sign off and get some sleep. But if you get a low number, do post here as someone will likely be around. Tomorrow, before the shot, let us know and we can help you figure out a good dose. And I'm with Sharon...might be time to go vet shopping!
Overall, relax and breathe. You're not alone in this.
