A You Tube link to a film explaining how PCA affects us;

As much as I can remember it:

The alarm goes off, I groggily switch it off. I turn on the radio and slowly wonder why the sound quality is so terrible, blame the radio and switch it off. Eventually, I get up and have breakfast, as normal I grab my IPad to read the news, but don’t have the energy, or wherewithal, to switch it on.

I then just sit on the sofa, not thinking anything at all, until my wife suggests I go back to bed which do, staggering as if drunk. In bed I curl into a foetal position and some hours later, I come to in the same position. (Usually I am very restless in bed).

I get up, maybe eat a simple sandwich and stay on the sofa staring vacantly for the rest of the day. I never want to stay in bed too long in case I don’t sleep that night, which actually never happens as I sleep well after a foggy day. During the day my muscles will twitch sporadically, the health professionals still don’t know what causes this.

Eventually I go to bed utterly exhausted.
