You've had a second bout of hypoglycemic shock, sounding more severe than the last. You need to break the fast. After shock comes coma. The narrowing vision indicates you were close to slipping under. If you lose consciousness and no one helps you get sugar, you could die.
The craving for maple syrup was your body's way of telling you it was out of balance. If you took the maple syrup straight, it probably caused a blood Sugar spike that caused the liver to overproduce insulin. That would cause an even more serious blood Sugar low a couple hours later.
Very classic pattern for someone who is Sugar sensitive. Frequent urination is another symptom of blood sugar issues. Drink more liquids, so you don't become dehydrated.
Start monitoring your blood sugar levels several times per day. See how you feel at various levels, see how what you eat affects your blood sugar. You can manage this, but you have to listen to your body and get to know how it reacts.
Stanley did say that diabetics should use molasses rather than maple syrup. I'd extend that category to anyone with sugar sensitivities, alcoholics, carb addicts, etc. Perhaps future fasts should be based on veggie juices, not lemonaid.
