Nice idea. I want to try it. But no friend of mine will ever do that. 
Ditto <_<
If you buy a walltimer for 4$, and one of those cheap disco-toy thingys, you know, ordinary lamps that flash different colors (Not the moving one, the focused) and connect these- Then you put the lamp next to your bed, facing you and set the walltimer to power it up in 5 hours 
In my ears this sounds like a great idea.
sounds good
