Ok, I have attempted this before but seldom more than one night in a row, and I get the sense it's something that really needs practice.

The first night I was pretty tired when I went to bed. I began to go into a meditative state, and practicing scanning the body for tension etc, but my mind kept wandering (a lot more than usual) and I kept drifting off and waking myself back up. I recon it would be much more productive to go to bed before I get really tired so as to get into the practice before I start drifting off.

Interestingly, I had a dream where an 'expert' described me as a 'sadistic pacifist' - thanks subconscious! I found this rather amusing, but in some ways it describes me very well. I have a fairly calming outer appearance and a fairly 'live-and-let-live' attitude, but there's also a spark there - a part of me that delights in pushing peoples buttons.
