My 2nd night of testing 10 units of Levemir was a success. Even though my starting blood sugar was higher than normal, the correction I gave myself was perfect.
BG at 11:20pm: 193 (2 unit correction, 10 units Levemir)
BG at 12:10am: 163
BG at 9:10am: 111
BG at 12:45pm: 165
As you can see, my number only came down as a result of the correction and afterward it stayed steady. No further insulin or sugar cubes were needed.
