Took Sebastian back to recheck his sugar level. I took him in at 4pm deliberately. He had his breakfast at around 9 am and no treats all day. I figured if he has hypoglycemia, it will be definitely showing 7 hours after he ate. And his sugar was 73! At the low end of the normal range but that is what I'd expect after not eating for most of the day. So, we are good and my wallet feels better because recheck was free.
