Nothing to offer, but you have my sympathy. As a raging insomniac, I usually do events - cycling, running, even trips out skiing* - on little or no sleep. It's become standard function for me.

* Home is at 350' elevation - first 4 nights or so at 9'000' in the Rockies usually lead to no sleep. I think by night 5, it's just sheer exhaustion that knocks me out.
