Yesterday, J just kept creeping up. I had been at work so didn't know he had been high for several hours. I got home and he was in the 300's. I bolused him and figured it was just something he ate that he didn't bolus for correctly. Checked him an hour later and he was in the 400's. Bolused again with a site change in mind if he didn't come down. Next thing I know, his meter is greeting me. Hi. Ugh. Changed his site, and he came down fine. No kinks I could see in the canula. Then last night, the receiver for his wireless mic we use with the Dexcom (which had been giving us ??? during the highs last night so we changed the sensor) had fallen off the table I keep it on. I picked it up in the dark, put it back and turned it on. J came in at 3:30 this morning having been woken by a low that the Dex showed he had for several hours! Under 55, and the Dex said 39 when I went to input the BG. He was headed straight up without eating anything, so I guess his liver dumped some glycgogen. (or whatever it is called - no sleep lately and my brain is sluggish). I gave him a couple of tabs anyway and he stayed in the 100's after that. What a ride.
