I know it can be incredibly frustrating, but all you can really do is continue to work the protocol. I have to wonder if the drop last night (from 188-109) in just 1 hour would have been a good night to plan on getting more tests in because that's a fast drop. He may have gotten down into green last night and was just working his way back up by AMPS time and then the bounce finally kicked in
What I'd suggest is to look at your spreadsheet and find places that have too much white, and start sprinkling in some tests to "fill in" those spaces...I know at night it's a real pain, but setting an alarm to get up and get another test or two in could possible help figure out what's going on with him overnight.
Hang in there! We've all been where you're at tonight.....May I suggest an adult beverage? Or some chocolate?
