I had mine yesterday, AZ - felt ok all day, just a bit tired. Slept reasonably well and woke up/got up with plans for the day (dog walking) but after being up a short time I felt pretty rough - achy and exhausted. So I will be taking it very easy (unheard of for me, like many of us I suspect) - reading, resting on the sofa and drinking lots of water.
As an aside issue, I suffer so badly from health anxiety and have had a terrible week worrying about the appointment so am actually quite proud of myself for just getting on and having it.
