Hello, I am T1 diagnosed few months ago. Last night i had these crazy jumping sugars. It did not even wake me up, but I am quite confused to what happened and I feel slightly worried going to bed. This happened before a few times, basically ever since coming back home from hospital I kept on reducing my tresiba dose that I take before bed.
I have read before that the Libre records low readings when you lie on it.
You may want to set an alarm to wake you up and do a finger prick test to check these results before panicking.
I have noticed this a few times while in bed. I have a nightrider also so I am woken up when I approach 4mmol during the night, I have been woken a few times when the sensor tells me i'm 3.5, but after finger pricking, i'm in the high 5's. The suppression and heat on the sensor can give it some weird readings.
Worth setting a couple of alarms though and experimenting with sleeping on the arm, or even just lying on it for a while, it may be that.
I find it incredibly useful, more so that I just don't have to swipe my arm all the time, even if it's 0.5 to 1mmol out, which it's rarely that wrong, it'll alert me and so on. Gives me some piece of mind when in bed or out walking.
