hi there, was wondering if anyone had this symptom before, im always really tired when i go to bed because i work quite long hours and fall asleep no probs, but after 2-3 hours i become awake in a panic not being able to get my bearings not knowing who or where i am what day of the week it is or even where i work and after that spend most of the night half sleeping but anxious and still dreaming its a strange off shoot but never had this before also if i become tired i fall into the same state and become slightly sleepy so its almost if i jolt awake?? any suggestions?
