27? Wait, test again!

I like our yoga class being an hour later this semester. However…Might I just add that I need to remember what I did to make sure my blood sugars were okay last semester? Let’s see, I drank those “Glucerna Glucose Control” shake in the car, while stopped at red lights in our car, bolused when we parked at the UNLV Parking Garage, and started the class with a blood sugar of about 250. Right, having enough time to eat an actual breakfast and bolus for it, and wait about a half hour to an hour or so until the class starts is much different than a couple of minutes and a brisk, no really fast, walk to the class. This morning, I ate cereal with plenty of carbohydrates to cover the 7.5 units I bolused, plus a banana. I tested before I drove us to school, of course, and was fine to drive. We parked, walked to the class, and on that last turn inside that building, I pulled my wristlet out of my purse and started to test my blood sugar. It said i was 212. Not to mention wearing the Sensor and having it say i was 192. ‘Nice, ‘ i thought to myself, ‘i should be fine.’This morning’s Hatha Yoga class, the third yoga class of this semester, was nice and relaxing, unlike the kick-boxing class that is totally a different stress level. Any way, I’m babbling, and I’ve been doing that lately. Okay, back to Yoga. The class was great. At about 8:30, we put our shoes on, carried our backpacks to the Women’s Locker Room, changed, and I tested.   Again.  My cute little meter read, “27″  Still standing, totally aware and quite conscious, I said to my sister, Jackie, “Uhhh, Jack? I am 27!”She stops fixing her hair and turns around and says, “What??? Wait, that can’t be true, test again!”I didn’t think I was that low either.Jackie must have that instinct, saying. “you don’t look low at all, you’re not even acting low…”I tested. Again. I waited the dreaded 5 or 7 seconds, and I said, “Jack? It says 30, now!”
“Well, I like that number better, let’s go with that. You need Juice.” And she rummages through her backpack and pulls out a big bottle of apple juice. “Drink half of that, and why aren’t you sitting down already?,” she says.  (My guardian angel…Jackie Jackie Jackie. I love you. Thank you for taking care for me.) She made me eat her snack, a “Breakfast Cookie,” which was somewhat healthy, because of the raisons, but it didn’t matter at this point. We sat there, waiting for my number to come up. All the way to 88 in 25 minutes. Then 104 eventually. What’s frustrating about this is that I didn’t see this one coming. I couldn’t feel the low. I couldn’t feel my hands being clammy, and I was walking, faster than Jackie.   (This is normal when we’re going to class, but when I’m low, I walk quite a ways back from her, and she notices, so I’ve been told.)I couldn’t feel it? Why wasn’t the sensor picking up this very low blood sugar number?
