Hi axoloti,
Yes - I actually have an appointment with a neurologist for next month so hopefully they can shed some light on it. One of my colleagues is already drving me nuts this morning, talking about 6 million decibels whilst using the phone and constant pen clicking - I have politely asked him before about the pen noise but alas it still continues. I have concluded that he is simply a moron, unfortunately I am surrounded by a number of them.
Roll on Chirstmas !
