Seems like not too long ago I was doing overnight basal checks. Truth be told, I'll always have to do basal checks to make sure I'm getting the right dose. It's not a "one time and you're done" type of deal.
So it went pretty well. I love love love the nice straight line I had the whole time! My numbers were pretty beautiful, although I did have to take 2 sugar cubes to keep from going under 60, so I think that stopped the test, technically. Anyway, it was a very informative check.
To start, I had my last meal at 5:45pm and didn't eat anything (just drank water) or bolus any Apidra after 8pm last night. My numbers stayed pretty consistent the whole time I was fasting.
Here's the graph with fasting prior to midnight, and into the test.
5:45pm - 96 (3g carbs, 2 units Apidra)
7:50pm - 85
9:10pm - 76
11pm - 86
Midnight - 79 (5 units of Levemir)
1am - 88
2am - 84
3am - 72
4am - 64
5am - 60 (took 2 sugar cubes = 4g carbs)
6am - 69
7am - no test
8am - 75 (5 units of Levemir, 1 cheesestick, go back to bed)
11:50am - 81
This graph is from Test Beginning to Test Ending, and a little bit beyond.
I'll obviously need to repeat this test 2 more times at least just to make sure but this test showed me what's really going on, at least last night. An ever so slight decrease in those first 5 hours.
(Ignore the incorrect date at the bottom of the graphs...my Dexcom didn't reset correctly with the time change. Ugh.)
