Hi all,

I've been diagnosed with Type 1 diabetes for about a month, I've got used to daytime glucose readings and on the whole these are pretty good (~80% time in range).
It is just the nighttime, I try to ensure it is above 8.0mmol/mol, may have a snack around 10-11pm just to last until 3/4am until the DAWN effect kicks in but still have hypos every 1/2 nights which is exhausting me.

Questions:

1) Even though my levels appear high enough at 11pm/12pm, I'm still having hypos during the night usually around 2-3am - I've reduced my tresiba from 4 units, to 3 units and been on 2 units for four days now (I'm in honeymoon period). My novorapid is only 1 unit TDS, I'll only do 2 units if I have a massive meal such as pizza (100g carbs) but this does seem to bring on early morning hypos even though rapid acting - any advice for this as a whole? I'm reluctant to reduce to 1 unit of tresiba just yet, as my night baseline can be flat if no hypo. Maybe eating late in honeymoon period is causing insulin to be released late?

2) My libre on the whole has been great, but I lay my phone on the floor and not bedside table just to make sure it will definitely wake me up and I won't snooze it. On two occasions I worry for safety now, as I am alone in my flat. The alarm has triggered and when I do a check, it reads 3.7, 3.6 even though my lower limit is set at 4.3. These were genuine hypos as I had a crashing headache and felt anxious, desperate for something to eat. What is happening to the sensor, does it lose signal through bedsheets do you think? Any advice would really appreciate thanks. I also worry I will not wake if my libre 2 does not go off, I know in another thread people say they would always wake... but with me I haven't yet only with libre alerting me at 3.6ish.

I can empathise with your experience. Hypos can really debilitated.
The Libre Sensor will always lag by about 5 minutes as compared to capillary testing from a finger pick. Try setting alarm at 5 mmol.
One thing I have learned after decades is that we are all different and that there are many variables in getting to the same outcome. Eg metabolism, stress levels, effect of exercise etc etc.

Thank you for the information about Libre sensors this explains a lot! I will set my upper limit higher :)
