Thanks BB , I will do exactly that ,put the kettle on make a cuppa and read your article . I could be doing with an uplift right now as I feel quite edgy and flat at the same time . We had a little family thing yesterday , my wifes dad,s anniversary (passed 9 years ago ) ,we like to celebrate his life playing his old Irish songs with a toast to him . I went into a strange mood ,like completely grey and spaced out ,wanted everyone to disappear . They did ,along to the local pub and I was left alone watching BS on the TV . Went to bed early and woke feeling better but still not 100 percent alert . Must be the winter .
