I have a colleague that gives me a headache.It is the frequency and tone of his voice that does it. Additionally, he is annoying, so the content of what he says also contributes to my headache.What is the best way of dealing with this please? I have tried Nurofen and Paracetamol, but neither have a noticeable effect.Thank you.
