Had an appointment with a GP yesterday afternoon. The doctor was quite firmly of the opinion that I was experiencing a reactive depression, an understandable response / reaction to the debilitating neurologically rooted myalgia, and the accompanying lack of refreshing sleep, which has been my companion for such a prolonged period; she prescribed 15mg Mirtazapine to be taken at bed time.
If the first night's anything to go by they have a wonderful sedative effect and should, hopefully, help bring about a resolution of my sleep deprivation problems. Last night was one of those very rare experiences where I remember very little between putting my head down on the pillow (lateish Friday evening) and slowly, but somewhat groggily, emerging into mid to late morning (Saturday).
I must admit that, at first, I felt somewhat as if I'd been sledgehammered; it took until mid-afternoon before I started to feel properly awake.
