Blood sugar dropped to 41 while sleeping

Am

Something in me was telling me to get up and check my blood. At 4am I did and it turned out at 41.

I had never seen it so low. I’m not diabetic and my doc says all I have is reactive hypoglycemia but idk each time I’m less convinced.

Before sleeping I didn’t eat much because I wasn’t that hungry, I ate the three little pizzas in a lunchables box.

I’m so scared of it dropping like that again and me not waking up.
