I occasionally get hypoglycemia. For me, it tends to be worse if I eat a lot of sugary foods the day prior and then go through a prolonged period of not eating. Like if I eat ice cream at night and then skip breakfast.

One trippy thing to try is to go on a keto diet. When your body is in ketosis, it stops using glucose as an energy source, so you shouldn't get hypoglycemia. It's actually a strange feeling. In my case, my energy level feels much more constant throughout the day.
