She also says that she has trouble falling asleep and wakes up several times during the night. She claims that this state of affairs has severely hampered her productivity and is a major problem for her, and she feels tired and fatigued all day. She denies hearing voices, abnormal thoughts, or any other psychotic symptoms.
