I'm started the P90x program after a little too much of the good life. I have been successfully wearing the Dexcom unit in my upper arms until a couple days ago. It seems that with the amount of heavy exercise I am doing the Dexcom readings become quite varied.
An hour after exercise I had a reading of 187 on the CGM compared to a 97 via the finger stick. I saw this variation throughout the day, so I can't contribute it to a fast falling BG due to exercise.
Anyone else experience this?
