COVID 19 jab

I had the AZ exactly 1 month ago.  I was very reluctant to have it, not because of the clotting issue but because of the lower efficacy.  Anyway, decided that it was the right thing to do and that I wasn't going to be offered Pfizer anyway at 57 so went ahead.  Of course, a week or so later, Pfizer was opened up to my age group.  I felt very unwell for a couple of days - headachey, muscle aches and very tired.  That did improve but I have to say that I have not felt particularly well ever since.  Not bad enough to go think I've got clots but I fatigue has been shocking (and I already get tired enough), I've had so many headaches and achey legs.  While this outbreak worries me greatly (good on ya, Glad), I am really not keen to get a second AZ jab.  Elsewhere in the world, they are quite happy to give Pfizer as the second one after a first of AZ and supposedly, the efficacy is better than two AZ.  I have a GPs appointment a few days before my second AZ so will see what he says.  I don't hold out much hope but quite possibly going to cancel the AZ.  Has anyone else had ongoing problems since having theirs?
