The difficulties of being an aging night owl

I have always been a person who functioned better in the evening than during the day. That first, beautiful ray of sunlight that peeks over the horizon at dawn? Never see it, unless in my youth, when I had been out all night. Then I saw it through bleary eyes as I was falling face down onto my bed. I love the quiet and stillness that the nighttime brings. The children are asleep, as are most of my elderly neighbors and I'm left in glorious solitude.
It's possible for me to function on five or six hours of sleep. My dear husband requires at least 8 hours. My children need 12. Left to my own devices, I will stay up until 2 a.m. and sleep in 'til 11. But we're never left to our own devices are we?
Most of the world insists on keeping to a day timers schedule. Schools. Doctor's offices. The people who come to work at your house. Everyone assumes that you're a morning person. Except that when everyone else is winding down, I'm starting to wind up. According to the schemes of the world, I'm supposed to be bright eyed and bushy tailed after having eaten a healthy breakfast and exercised at the gym and showered. And I'm supposed to have done all this by 7 a.m.
And then there's the children. Those tiny human beings who spring from their beds and are ready to face the day. They decide that you should face the day at the exact same time, no matter that your aging body, dehydrated from the amount of Diet Mountain Dew you guzzled the night before, is screaming at you to stay in bed.
Therein lies the real issue: being an aging night owl.
I can honestly say that I crave the energy I had in my 20s to be melded with the wisdom and life I've gained in my 30s. Because in order to keep up with the daily demands of the day timers and get any of my precious nighttime solitude, I must consume large quantities of caffeine. Like some heroin addict, I need more and more of the stuff to keep going and reach the wakefulness that one can used to bring me. Twelve ounces of Diet Mountain Dew simply doesn't do it for me anymore. Now it takes two or three cans or perhaps a pot of coffee, a fact I keep from my urologist so as not to alarm him.
Where will it end? By my 40s, I very well could be hitting up convenience stores and stockpiling energy drinks. Although my older girlfriends tell me to enjoy the sleep that I do get, because someday hormonal changes will bewitch my body and sleep will come not at all. Perhaps then I'll replace my Diet Mountain Dew with a few cups of chamomile tea.
