So with the gaps in testing and some of the numbers, it's a bit hard to advise. I suspect he may be hitting greens and then bouncing. That said, realistically I think you may need to look at Lantus/semglee.
If you want to give ProZinc a final try, here's what you'll have to do:
- A curve once a week or close to it. That's testing every other hour for 12 hours.
- A before bed/before you leave the house test each day, for most of us that's a +2 or +3.
After 2 curves and the data in between, I'll be able to give you a better opinion if ProZinc is even worth putting more time into, and how to adjust dose.
Or, you can say forget it I'm done with ProZinc, I want to try Lantus/semglee. In which case once you switch you'll still need to do the tests I mentioned above, and here's the reasoning -
I suspect you're fighting some glucose toxicity. His body has been accustomed to the higher numbers and now considers them "normal"...so he gets stuck there. And so holding the dose too long, like you have possibly been doing, is counterproductive. You have to keep methodically increasing (as long as it's safe) until you hit a breakthrough dose.
