Patient: occasionally I drift off to sleep nice and relaxed and wake up from a deep sleep feeling like someone has hit me in the chest with a sledge hammer and can feel my body jump from my bed and fall back to the bed with a heavy thump and I wake wide awake with my body dripping wet in sweat from head to toe and realise something serious has just happened Doctor: Hi, Welcome to Health care magic forum.                   The condition you are facing may be called the narcolepsy,caused by the  lacking in hypocretin, a chemical in the brain that activates arousal and regulates sleep. . Narcoleptics generally do not have as many Hcrt cells to produce hypercretin, which accounts for his or her tendency to fall asleep.                   The investigations to diagnosis are Nocturnalpolysomnogram,Multiple sleep latency test,and Spinal fluid analysis .                  I advise you to consult a neurologist for diagnosis and treatment. You may need to have a C.T.scan for diagnosis.                  The treatment comprises are 1.For arousal Modafinil,and sodium oxybade.For antidepresant activity-fluoxetine,and sertralin.                    Wishing for a quick and complete recovery. Thank you.
