For people who are on Macs, theres a nice application that you can use for the custom alarm. Its called Apimac Timer (http://www.apimac.com/timer) and its basically an alarm clock that rings once (or twice, or up to 5 times, check in options).

Im gonna try this method this morning. I set Apimac Timer to ring as "Purr" 4 times. That seems to be the best option. The purrs are about 1 sec apart and are a soft but distinctive sound. Should work fine.

Awesome guide, looking very much forward to trying this. I will prolly have no difficulties what so ever in not moving. Im a natural sleeper

Thumbs up, thanks for the great idea
