NO spreadsheet (SS), no signature, need those 2 things setup first, to see what is going on with Sophie.
How to do that setup is in this link
FDMB Spreadsheet Instructions
What it means is here
Understanding the Spreadsheet/Grid
Updating your signature is here:
Editing your Signature, Profile, and Preferences
We like to see your first name, your cat's name, age, sex; DX: diagnosis date; insulin used, meter used for testing, diet, and other medical conditions we should know about. Once you get your SS setup, you put a view-only link to it in your user id signature.
To edit/setup your User Id Signature, go to upper right corner of screen, click on your user name, drop down list appears, select "Signature" from the list, text box appears. Type in the needed information, and be sure to click on "Save Changes" when you are done. Takes about 60 seconds to do that.
Would you do that little bit of work please? It will help us help you better.
p.s. If Sophie did not get insulin this morning, there is no insulin in her to cause her to go low. She is safe from hypoglycemia.
