Can I ask why you're increasing the dose?
There are 2 ways to earn reductions....One is by dropping below 50 three times (or below 40 once) for a long term diabetic like Henry is, or by staying in normal numbers for 7 days. (50-120 with most under 100)
I didn't look all the way back, but I don't see any test results out of the normal range when he was on 1U so he could have been reduced to .75.
