Great blog.

consider getting yourself checked up

Definitely. Sometimes, it's not 'all in your head'.

I've been dealing with an autoimmune syndrome for almost 40 years. Sometimes, the first thing to go is sleep, before a flare. Once, I stayed up all night, literally without sleep. When I went to the doctor's the next morning, I hadn't slept at all (couple of other minor, telltale symptoms, but nothing remarkable). She gave me a five-day tapering dose of prednisone and the episode was over.

Sound mind, sound body. Sound body, sound mind :)
