They have checked my thyroid, and my sugar. They said that it is not diabetes or thyroid problem. But if I am not up and moving. If I just sit down I can basically fall asleep. I am fine if I have some one to talk to or a puzzle. But if it's just sitting here. I feel drained. Like now my face feels heavy my eyes droopy feet tingly and very tired. But I sleep more than 8hrs a night.
