I like that approach. I think too many people force themselves into a rigid sleep schedule. Sometimes I need more rest. Sometimes less. Good idea on the water. I have heard cold water is hard on the system first thing. And most people go straight to a stimulating drink. Sound like you have a solid non-ritual ritual.

What gets you up in the morning?

My father wakes me up in the morning generally. But sometimes I get up own my own if I sleep early. I've no hard and fast rules about when to sleep and when to wake. I take it more naturally. If I sleep more, I think it was required. If less, it was not required. Yes, after waking up, I drink 1 glass of lukewarm water.
