Ask HN: Extending the morning rush of ideas

I've observed for some time that the majority of my good, creative ideas come within the first minute of my day. From about when I swing my feet out of bed until shortly after I jump in the shower a dozen thoughts rush through my head of a quality that I rarely experience for the rest of the day. Unfortunately, as soon as I realize that I'm in this state of mind it disappears completely. I've read that this is fairly common and imagine that many of you experience it as well. Is there anything you can do to either extend the length of time you're in this creative flow or get back into it at other points throughout the day?
