Thats interesting, Letum. Reminds me a little of Sherlock Holmes, actually.
Anyway, I have been experiencing a major shift in my sleep patterns, and I dont think my body knows what to do with all the extra time its gotten. I used to have to get up somedays at 6:30 to be in to work on time, and the days were very busy.
Now my contract is up, I'm unemployed again and obviously have more time for sleep (pain in the ass trying to get work here if you dont drive) and over these couple of days I've been dozing off at 10pm and waking at 4am and I'm unable to get back to sleep. I did it again this morning, I woke at half 3 even after I had a great many beers the previous night
Give it some time, your bio-clock needs to adjust to what you're giving it. I wouldnt think serious medication is the answer just yet, maybe just dunk a sleeping pill When you REALLY cant stop your mind working. Things should fix themselves in time.
