I have had bouts of insomnia for many years. More recently due to an enlarged prostrate I wake several times a night. When I wake up it’s as if there is a puzzle to solve, like I’m half asleep and still partly dreaming. I tell myself that there is nothing to be concerned about but I still lay awake agitated for long periods. Typically I finally get some restful sleep from about 4 to 6am. My wife often tells me that I fidget in my sleep. I have never resorted to medication but as things worsen I am considering it.
