I have been told it might be this bisoprolol which is giving me these bad headaches so going to change..... not sure what to, they seem to not agree with me.
Blood test this morning I'm 1.3 so will see what it's going to be, having done my research I do not worry about it as I did, it's all the matter of learning about AF then just getting on with our lives looking after my self at the same time.
Best wishes to you all... keep well.
