This is really just a follow-up to my post on Psychosomatic Disorder. This post generated quite a lot of discussion, and I happened to mention in one of my replies that it's useful to know how to deal with stress.
Some years ago, I worked at a private psychiatric clinic and one of my colleagues was a psychologist called Reinhard Kowalski. He publishes books and I recall him producing relaxation tapes, which I found very effective.
It has just prompted me to search to see if these are still produced. If anyone is interested, have a look at this about Reinhard Kowalski...scroll down the page and you will see that relaxation tapes are still available.
