It was, as you said, nothing. And hurray, seemed to have a pretty quick effect. Since yesterday morning I have walked the dogs three times, further, faster and uphill! Now for the first time stopping every now and then because breathless as before I could only go for such little walks the breathlessness never kicked in.
Also picked 2Kg elderberries whilst I was out, now destalked and in the freezer ... elderberry wine and perhaps some syrup I think. I love doing those autumn 'preserves, pickles and chutneys', not done wine for years, but have been given demi johns by a friend so brewing time is here.
Hope you are all as well as poss, and getting out and about if you can. Weather is closing in fast here, wind up and about to chuck it down I think ... so now going to check out the TV.
All the best
