RSI update.

Thanks to all the tips and recommendations my RSI is now much better. It no longer hurts at night and apart from a little stiffness during the day is quite tolerable. But I have had to change my life. Everyday I make sure I stretch and take exercise, sit at the computer properly and take frequent breaks. It is quite a regime, but worth it if it means I can carry on writing. Thanks to everyone who gave advice - it was much appreciated.
