Recently I’ve been using the Sleep Cycle alarm clock iPhone application. The app uses the iPhone’s accelerometer to analyse your sleep and wake you up when you are in a light sleep phase (near your specified alarm time).

This morning I noticed some amusing patterns based on my state prior to going to bed.

It’s worth noting that I have a broken clavicle so I do not move too much whilst resting.

A regular night

Speaks for itself and most of my graphs look like this.

After a dose of paracetamol+codeine and muscle relaxants

I was in a lot of pain one evening so took the prescription medication before retiring.

Out cold!

After having a bit too much to drink

It was a friend’s 30th birthday last night so I had a few alcoholic beverages.

I woke up lying on my broken side with the duvet lying on the floor.
