Having a bad two days:being stuck in a Fog

I am currently in a "fog" and wake up tired and sleepy.. I seem to be waking up every night at 3-5 to use the restroom. half the time I am awake for another hour or two. On Monday, I saw a new Neurologist. Woke up at 4 am On Tuesday, I saw the Eye Dr and went to the Post office. Up at 5 am and took a 2 hour nap in the afternoon On Wednesday, Took photos at local garden. Was up at 4 am. I also took a nap from 1-3. On Thursday I woke up tired. I went to UPS, picked up a prescription and got the car washed. I was up at 5 am. I took a nap from 1-4. Went downstairs and fell asleep again for another hour. I have been in a Fog since Thursday. I slept 4 hours that day. Any ideas?
