Thank you awuh1, dwtbd and Dee. I'll certainly do something or other.
RR/AVRT - I know nothing of any such things. I have drunk a lot but I honestly have no knowledge of clinical stuff. I obviously have suffered from having a fixed idea that no one can teach me anything.
It is time for change or, well nothing really. I actually feel better now than I have for a long time. It doesn't matter. Bring on the cheerleaders.
