Interesting

he probably did get some in.
Why did he think it was a FS?
Just a thought about the dosecrease, with bfg it usually took about 3-4 cycles for me to see the effect of the dose change.
She's been on the 4u for a little longer than ideal for TR, if you take her up tomorrow it will have been 12cycles rather than the 6cycles her numbers warranted, I know that there has been 'complications' I'm not criticizing, just an observation. But the longer she's in higher numbers the more probable that she develops glucose toxicity and the harder it will be to pull her BG down, and the more insulin she will need to pull her down.
So if it were me I wouldn't delay the dosecrease. Just my two cents worth.
