I had a discussion with my CDE after reviewing the chart printed from my BG meter. My A1c was high this time (8.0), and after taking a close look at all of my numbers, we've concluded that I am correcting my PP sugars too soon. Many times if my CGM gives a high number two hours after eating, I will cover myself with extra Humalog. Many times after, I'm low. She made me promise at my appointment not to treat a high for four hours after I eat. I was very reluctant to agree to this though. The first two nights after dinner, I started noticing a decline after three hours and never needed any extra Humalog. Last night, at the three hour mark, my sugars seemed to be holding strong at 230, assuming I wasn't going to see much of an improvement in one more hour, I took 1 unit of Humalog. 40 minutes later I was at 60. I was so mad at myself for not waiting, as I'm sure it would have come down on it's own. My question is, if you need coverage after a meal, how long do you wait to take it?
