1.1 and I was a mess but not hospitalised, was hospitalised when I passed out from low blood glucose about 10 years ago but no idea what the figure was.
It was somewhere in the 1's, possibly I.8mm but I don't remember the exact number as it was a long time ago. I've never been hospitalised due to low bg or had any third party assistance, more through luck than anything else.
I've had a LO on the meter once. 15 minutes later I had raised it to 1.9
Thankfully I wasn't hospitalised. In fact I was completely "fine". I was walking the dog and I managed to get some lucozade and calmly make my way home.
I phoned a friend while it was happening so that some one knew where I was if things went downhill. Just in case!
I think I've posted pictures of a 1.7 or 1.8 on twitter before now.
Didn't need hospital treatment, just glucose tabs. I did feel awful at the time and for quite a while afterwards.
