[QUOTE="KennyA, post: 2748531, member: 517579"] I get the very low BG in the early mornings. I'm T2 on no medication, and as of April this year I won't have had a BG out of normal range for five years. The sweats etc. started around 2014/5, not sure. When it happens, I get nightmares and really extreme sweating - it happened last night after about a six week break. Until I tried a CGM a few years ago I had no idea that these sweats coincided with low BG, but they do. There isn't a great deal of knowledge about this, but I do know from my local low carb group that some non-diabetic people who've used a CGM have reported exactly the same thing: a sudden cliff-edge drop in BG that lasts minutes, if that, followed by a very steady rise that seems to turn into dawn phenomenon. There is some "confirmation" of this in research: [URL unfurl="true"]https://pmc.ncbi.nlm.nih.gov/articles/PMC7296129/[/URL] This piece of research is on non-diabetic people using a CGM, intended to establish a sort of baseline and an idea of what "normal" looks like in modern CGM use. You'll see towards the end in the "Discussion" section they mention that there were a number of these "very low BG in the early hours" incidents, which they found a bit baffling, the subjects being non-diabetic etc... It's often put down to "lying on the sensor" but I don't think that lying on the sensor explains what causes the sweats and nightmares - which are exactly what you'd expect from an actual low BG. I think this is an attempt to "explain away" rather than to really explain what's going on. [USER=582816]@Jasmin2000[/USER] suggested to me in another thread this fall in BG could equally be caused by a increase in insulin - but no-one seems to be interested in doing any work on it.
