In a book called “The Verneys“* by Adrian Tinniswood (highly recommended) he quotes the following entertaining story from the 17th Century:

Thomas Sydenham, a Parliamentary cavalry officer and also a prominent doctor, had an aristocratic patient with deep depression, which nothing seemed to cure.  The good doctor interviewed the patient in London and referred him to a Dr. Robinson in Inverness.  The patient duly embarked on what was then a long and arduous journey, but when he arrived in Inverness he discovered that there was no Dr. Robinson in the town and thgat he had totally wasted his time and money .  He was naturally furious and rode back again to London post-haste to confront Dr. Sydenham.

“My dear Sir, said the good doctor, your eagerness to see Dr. Robinson preoccupied you while you rode north, and your rage with me consumed your waking hours as you rode south to remontrate with me.  Have you not completely forgotten your depression?”

Note:  The Verneys is an account of three generations of an English landed family from Buckinghamshire that covers the reigns of James I, Charles I and Charles II.  Letters between the members of the family were all kept and re-discovered in the 19th Century. For an historian they are fascinating and help to explain why so many Englishmen escaped to Virginia (among other things) .
