Hi, I have hypoglycemia and if for example I don't eat anything I start feeling shaky and heart starts pounding. Some nights when I go to sleep I don't fall asleep until it's like 2 in the morning I fall asleep and when I wake up in the morning like at 8 I don't feel tired at all. Usually I'm very tired and I fall asleep without any problems. Could this be insomnia or hypoglycemic or what does it mean? It's been two nights I notice such thing? What do you think I should do? I can't understand what is this. Please let me know soon.
