Nadine, I had asked you earlier in this condo but you haven't answered yet
Why did you reduce from 2 units to 1.5 the other night? While it IS possible that Tibbs might be going lower at night and then "bouncing' back up, instead of reducing, I think it would have been better to just start getting more of those PM tests.
It's great that you got an extra couple of tests in last night! If you can keep getting at least the +2 in, that'll help. I don't mean to ONLY get a +2, but that test can give you a pretty good idea of where Tibbs might be going later on in the cycle.
You also say on 8/27 that he's "Almost" off the dry....is he getting ANY dry now?
Just compare the +2 to his Pre-shot...If the number is lower than the Pre-shot (by more than just a couple points), that's a good "early warning system" that he might be going even lower later in the cycle and those are the nights you'll want to make sure to get more tests in
If the +2 is about the same as the Pre-shot, usually that means a more normal cycle with the number gradually going lower and then gradually going back up. On those nights, grabbing one last test right before you go to bed will probably be enough
I'm glad you're testing for ketones, especially with him running as high as he is. If you catch them early, you can sometimes handle them at home (but we all hope he never had them!)
We don't want him to continue staying in these higher numbers any longer than necessary so we lessen the chances of glucose toxicity setting in, so if you can get a couple of tests in tonight, if he doesn't come down into blues, I think I'd increase him back up to 1.75 and see how he does for the next 6 cycles.
