Hi Christina
I remember the day chocolate went really low and the reduction was advised. You've done a really good job of sticking with a dose since then. It looks like you've proved that. 4 and .6 were not high enough, so upping to. 8 makes sense. If you don't see an improvement in the next 2 or 3 days, then going up to 1 would be good. I think what's going on is that her liver is so used to 250ish being normal, that any time she goes just that low it is panicking. Today's curve looks like that is what happened. If you stick with trying to push her down to blues mid-cycle, hopefully her liver will quit fighting you.
