Guppy took a HUGE dip, 40 at +6, gave some medium carb with a little karo syrup. Had also given medium carb at +4.5. No symptoms as far as I can tell. Will test again in 20. Reducing in the morning, would it make sense to give 1.5-2 units in the morning to deplete the depot a bit? These crazy dives at night are concerning me, he's eating quite a bit and I'm giving larger snacks, but it doesn't slow the drop. He gets the same amount of food during the day, I don't really understand nocturnal hypoglycemia, is it just something that happens with no real explanation or is there a reason for it?
