I'm attaching my spreadsheet and hopefully it's readable. I don't have Google Drive set up. A lot of notes in the remarks. I reduced insulin to .5U since Feb 5th. Perhaps I wasn't testing at the right hours, but was doing a curve again and she dropped from 258 to 48 in an hour. I have her FF gravy and she was up to 69 in 30 minutes. She got .5U@8:30AM, looked good at 9:30AM and 11:10 she had plummeted. She's not a big eater on a per meal basis. Is it possible that her small meal to carry the insulin caused the drop?
