Hunger roller coaster

Megan
I was just out running errands and I got SO hungry I was nauseous and actually breathing through it. I picked up food, moaning and starving the whole drive home. I finally get home and have only gotten 10 bites in and already SO full. Is this normal or do I have possible blood sugar issues? It's frustrating! I try not to go more than 2-3 hours without a snack but when hunger hits I'm so hungry I'm sick and NEED food
