You may have sleep apnea, that is when you sleep but you don't sleep "deeply" enough to be rested. They say "deep sleep" is when you dream(lol).
I dream all the time so I am definitely in a deep sleep. Lately my husband is totally hogging the bed to the point of I have barely enough room if I sleep on my side and one leg is partially off the bed. Takes me hours to get him to move back to his side. I've talked to him several times about this. I don't have another place to sleep in our home - unless you count the backseat of my car which at this point would be more comfortable.
If it's sleep apnea I would assume I would be tired all the time - every day, right? This weird fatigue seems to happen roughly every four weeks. I currently don't have medical insurance so any testing is out of the question for now.
I think I am going to track my symptoms and see if they are cyclical. I do feel somewhat better today. My mood is a little more happy today.
