This isn't about brewing, I've just caught something that had knocked me for 6 and I can't figure how an earth it happened. I only ever go to pubs / shops when quiet and keep distance between the next person. IN fact when mrs DOJ caught covid and I was awaiting an op I didn't get it. The last time I had this lack of energy was after my bypass op. Hopefully I'll recover enough by Thursday so I don't have to cancel our scottish trip. So whatever it is 3 c-19 jabs and a flu jab haven't stopped it. Take care.
