I am halfway through the first week of my functional restoration programme. It is not Army basic training tough, but it is tough nevertheless. We were warned on Monday that our levels of pain may increase at first, that emotions would well up, and that we may have some negative feelings about the treatment. All true! Today we had a lecture about stress and learned that we may be experiencing random floods of adrenalin. Well, that may explain the two almost sleepless nights, despite being bone-tired, and the strange desire to do violence to DH, who has no idea what I am going through. Hormones mostly suck, in my opinion. And I say this despite having experienced pregnancy (thanks, I actually slightly prefer old age!) and having at least the memory of having a great sex life. The problems with hormones is that the good vibes they give you are far more than outweighed by the misery they can cause in other circumstances. YMMV.
