Hi Lisa!
Sue asked me to take a look at Ben's SS to see if I can take off my Lantus thinking cap, and put back on my ProZinc thinking cap. ;-) My guy Eddie was on ProZinc for about four months before we switched to Lantus. Eddie had some complicated dance maneuvers while he was on ProZinc, and he still does on Lantus. :lol: I try to pop into the PZI forum to say hi once in a while, and check on some of Eddie's PZI buddies.
So, a couple things I'm seeing...Ben did look better at a lower dose a few weeks ago, when he was hitting greens. However, there doesn't appear to be any green numbers for about three weeks now. I read somewhere that kitties often have a "honeymoon" period when they very first start insulin, where their numbers really look great right away, and then they sort of settle into needing a higher dose. I'm wondering if that might account for the greens in his first couple weeks on insulin.
Right now, to me, it looks like you have room to increase the dose - the caveat being that I'd wait to do so until you can monitor fairly closely...including at least 2-3 tests during the night time cycle. Kitties can "bounce" for six full cycles (sometimes even more), after a low number (or lower than they're used to), so if you happen to miss a lowish number during one night time cycle, the next six cycles can all look red and pink as a result of bouncing off a low - making it appear that the dose isn't high enough. For example, I wonder what Ben did during the PM cycle on 9/17. It's possible that he may have already been on his way back up at the +7 you got that night after going lower. Hard to say. I don't see anything that's super obvious to suggest low numbers during some of the cycles that there aren't any mid-cycle tests, other than some black pre-shots - which to me - say bounce. For example, Ben may have hit lower numbers during the PM cycle on 9/19 or the AM of 9/20.
Do you work days or nights? I work full time too, and I was (and still am) pretty aggressive with dosing, so even though my ability to test during the day time while I'm at work is pretty limited, I get as much night time testing in as I can so as to try to spot patterns. One thing we recommend with Lantus, that IMHO may be a good idea with ProZinc too is to shoot a little earlier in the AM (if your schedule allows), to try to get one extra test in at +2 or so before you head out for the door for work. A dropping number at +2 can signal a "busy" cycle, and some kitties seem to drop like a rock super early in the cycle if the dose is too high, and then start to head back up well before +6. That's another pattern that can make a kitty look flat when they're really not.
I'm a big fan of sliding scales, but for the moment, I'm thinking that you may want to try hone in on a dose that's at least in the ballpark, and then tweak with a sliding scale from there.
That's my two cents which is probably worth far less than that. :lol: I'll be curious to see what your tests tonight reveal. I'll be up for a while yet tonight, and will keep an eye out for Ben's numbers.
