I cannot remeber the last time I felt energized or at least completely awake. I am always tired no matter how muich or how little sleep I get ( i do have difficulty sleeping as well) but primarily I am always tired, unactive, dont have the strength to excersize and sometimes im even too tired to chew food. My fatigue is often felt in as a certain heaviness in the back of my neck. is this wierd? does anyone understand this?
