I've had it before...
One summer night at home sitting with 28mgdl... and I felt NOTHING until in a second I went skydiving!
I was always low like 80's 70's so I just came aware once when I raised the bs in general and dropped it again...I thought it was something like 10 cause it felt pretty bad than I was 28...but it wasn't... it was something around 60...
I would like to watch myself if I was taped watching that meter and storming the kitchen in the same second
