do you have any old BG readings from physicals in the past? hopefully not years ago...
go by that i guess? morning empty stomach BG reading ...as long as you are under the standard norm, you are okay i think... right?
if that number creeps up or you notice that you have to take more slin to get the same effect or your carb intake goes up,,,getting fatter,,,,sugar hungry etc
many signs...but i think you would need a baseline to go by.
perhaps not too late to start logging now if you are concerned.
