Sleep apnoea was the most likely cause for me. I thought I was a light sleeper for years, then was diagnosed with sleep apnoea.
A bad night could be 4 visits, now if I don't drink too much fluid in the evening, I can sleep through the night.
Really get a solid nights sleep now, but still half asleep during the day, start to wake up about 4pm(long story) not sleep apnoea.
I was told that the body shuts down to minimum during the night and it's when I was unbeknown kept waking up, that the body was still working, hence the kidneys flushing hte waste. Plus, being overweight and with diabetes, I can see my legs swelled when I go to bed, and ok in hte morning. This also depends on how much sitting around I do, which for me is difficult as I sit down for a job
.
Also suffered with serious night time sewats, soaking hte blankets, the missis had to sleep elsewhere, not had that for 3 or 4 years, I don't think it was related to sleep apnoea as it stopped before I was diagnosed. I reckon it's summat to do with cushings. Been feeling ok for 2 years now, not dead when i wake up in a morning. Hope it carries on as summat more than aleep apnoea is going on.
