We just passed our 3 year mark, and it still terrifies me when my DD (14) goes low fast. We have a Dexcom, she's on MDI - Levemir and Novorapid. The Dexcom has made things so much easier to predict, and treat numbers before they become a low, but there is still the odd time when she plummets and I wonder if I am treating it how others do. Last night, she had a cinnamon roll. I weighed it, counted the carbs the package indicated, calculated her I:C ratio correctly, but didn't factor in that we'd had a long day of shopping with a lot of walking. She quickly dropped, and her glucometer went from 15 (270) to 3 (54) in a little over an hour. I gave her a cup of ovaltine (20 carbs) at about 8mmol when I saw the big drop on the dexcom - kept dropping, then 24 c. of juice ...still testing and dropping, 14 c. of rockets (smarties)...still dropping and another 24 carbs of juice. Her reading finally started rising. I know the books (and I've read lots of them) say to treat with 15-20 carbs and wait 15 minutes and recheck, repeat if necessary. I am quite sure if I had done that she'd be on the floor and I'd have had the glucagon out. She only went up to 11 (198) after all these carbs, so I can't imagine how low she would have gone without that heap of carbs. I am just looking for anyone else's strategy when faced with a fast drop. Do others over-correct, then give a correction dose later? We are both pretty on top of things as far as day to day management, but I don't know if I will ever get over the panic that sets in when this happens! Last time it happened, we were on a cruise ship about 11:30pm. Now that's stressful.
