This is a companion piece to Maurie's discussion on his Low, called "Sobering...". Last night I was well and truly Sobered by Highs. When I was about to get ready for bed, I monitored and was 508! (I've been Type 1 for 21+ years.) Clearly my Apidra pen, which was mostly used up, had gone bad. I corrected with a new pen and a half hour later my BS had gone up to 537. I told my husband that we'd better consider the ER, but it finally, slowly, started going down. I drank 1 1/2 quarts of water and monitored until 3:00 AM, when my BS had gone down to 338; took a shower and went to bed. I woke up to a reading of 143 at 7:30 AM.
I learned a few things from that incident. One is that my Apidra kept working well beyond it's usual 3 1/2--4 hour active time. I didn't have any ketone strips, but I doubt that there were many ketones when I'd only been without insulin for about a half day. I found that I could in fact treat a bad High in this early stage of DKA, if in fact I got as far as being in DKA. Remember: never, ever forget to Test! Test! Test!
