Mandy and others,
Thanks for the question and replies. I've wondered this myself, as I am Type II, but have had lows a few times. I've always been fortunate enough to be coherent and get some sugar ASAP and everything has ended up fine.
For other Type IIs in the community who have experienced lows while taking only oral medication, what do you think is the leading cause of the lows? I don't know, but I think for me it's just been going too long without eating.
