I don't know if any of you have come across Mindfulness. It was recommended to me by my psychiatrist after I'd attended a psychology workshop. It is based on a Buddhist practice and you do it with a CD which guides you through the meditation which takes about 45 minutes. There is a whole department at the University of Bangor which runs studies and teaches how to practice (though I found it's okay just to shove the CD on and follow the voice). It is currently being trialled in Wiltshire as an aid to helping depression. It takes little effort (I do it lying on the bed) so you can still do it when you're quite sick. One of the principles that you use in practice is that "the present is the only time we have to be alive" which is where my signature comes from. I would heartily recommend it.
