happened again this morning, she threw up twice and her bloodsugar was 4.7. she refuses to eat and will only drink

I am 45 yrs old and also have the same problem,it is usually if i wake up to early, for some reason my sugar just won't regulate that early in the morning, i have also had it happen during the day if i have taken a nap. My husband usually gets me sweet tea and a cheese sandwich,I literally have to choke it down because my stomach hurts and i am so nauseated. I haven't found anything that works or stops it from happening. You sort of just have to live with it. My suggestion is if your planning on waking her up to have a glass of juice ready before she starts to move around.
