I had to get DH get up and get me some bread and butter in the middle of the night a couple of times and I had jatz next to the bed. What I found to be great and only stopped using them a couple of weeks ago are sea bands. They're available from most chemists and you wear them around your wrists, they work with a magnet on accupressure points.... I wore them all the time and only took them off to shower or bath. They can feel a little uncomfortable for a few days but then you don't notice them.

Fletch have you looked for them yet?
