well lets see, I was waking two or three times a night .. averaging 1.5 to 3 hours at a time totaling around 6 hours in all ... now ( for reasons unknown) I am sleeping 5 hours straight with no waking ... success you say ... except I am more tired now than ever before ... I am sleepy during the day and if I stop moving I fall asleep ... even with these "naps" during the day and my five hours at night I am nodding off all day ... and have had some impaired driving ... suggestions what to do ...
