I have not been looking for this correlation long in my stats, but I heard about it, and looking back, I am getting a spike from exercise. Check the following stats: (again, I have not tracked this for long, so only three entries)
06:21AM 127 mg/dL (Morning) Waking Up
08:38AM 150 mg/dL (Morning) After Activity
06:19AM 119 mg/dL (Morning) Waking Up
08:31AM 150 mg/dL (Morning) After Activity
06:27AM 128 mg/dL (Morning) Waking Up
08:39AM 162 mg/dL (Morning) After Activity
A little more info: I never eat breakfast (bad habit, I know…sleep is just too appetizing.), and water is all I ever drink before I go exercise. Anyone else deal with this? Any ideas? I will be checking before and after exercise some more to see if it is every day, but (thanks to Sugar Stats), I have monitored three out of three days where I have a spike after exercise.
