I have a suspect - afternoon coffee/too much caffeine.
Yesterday, I tested my blood right before I left work because I didn't feel good. I had had an afternoon half cup of coffee and a caffeinated soda in the afternoon after having a whole cup of coffee in the morning. I have always been sensitive to caffeine.
Anyway, Tested my blood at 4:45pm - 83, pretty low
6:15pm before dinner - 90
6:45 pm just after eating ground pork, cheese, sour cream, avocado- 97
7:30pm - 93
9:15am (woke up around 7am) didn't eat anything - 105
9:53am after drinking coffee with torani, 2 pats butter, 1/2 tbsp coconut oil, 3 tbsp heavy cream - 101
11:21am (nothing since coffee) - 90
11:45 am - ate 2 burger patties with cheese, pickles, tomatoes, mayo, and mustard from Burger King
12:25 pm - 94
I have literally no idea what these numbers mean though if anyone could help interpret. (@richard, my buddy )
