When you look at the spreadsheet, along the very top, you'll see the "blues and greens". So realistically, he was "in the greens" which is actually a GOOD thing! But, I know it scared the crap out of you in regards to how much he'd dropped from the morning (AMPS) test. So as Yong said, in the greens he had not crashed, but he did continue to drop lower and lower, which was understandably scary
My one question, and this will confuse some (but Rochelle and I are in the same city/time zone) was his PMPS test at 8:04? If so, it is almost too late to shoot now anyway. (Not that he couldn't have insulin if he really needed it, but if you're going to shoot, it should be within about 10-15 minutes of him eating)
Start fresh tomorrow, remember to BREATHE! Trust me, we've ALL been there. This is mind blowingly (my new word) overwhelming. So the fact you got your spreadsheet going and published is a great start!!
