I have noticed that if I oversleep like 3-4h. Or wake up take Metfor. And take BG measurement. If I then go back to bed for 3-4 h without eating any thing or I am busy with work (remote) then often when I measure again my BG is up 1-2 units. That confuses me shouldn't it go down longer I am not eating ? Or is it that body gos into "starvation mode" when you do not eat for too long? Or is it just stress?
