This evening we experienced our first low BG. Jeremy had all the symptoms. Dizziness, sweating, heart racing, saying that he feels like he will pass out. His BG was 52. I gave him a small bag of fruit snacks (19 carbs) which brought him back up to 121 after 15 minutes. I had visions of breaking open the glucogon and calling 911. It's good that it happened at home and not 30 minutes earlier when he was walking in the mall with his friend. Now we know what the low feels like.
