Hello doctors, past few months i am suffering from sleep attack like symptoms, even after having good deep sleep of 6-7 hrs, every mrning after waking up within next 2 hrs my eyes clench, i feel heaviness and sleepy in eyes so much that i have to lie down and close eyes and try to sleep for good hour or so to be functional for rest of day. I went to different gp doctor but no one able to diagnose the cause effectively. :( Please help.
