How in the heck do you do it? How do you get enough sleep in order to make the commute by bike?

My daughter is 9 months old now and going through serious teething at the moment which means that at any time during the night it sounds like a piccalo pete is going off in her room. This comes after contending with acid reflux, after her catching one heck of a case of bronchiolitis, and just being a baby in general. And all this after my wife went through a less-than-easy pregnancy where we were in and out of doctor's offices all the time.

Getting "enough" sleep just to function can be a challenge, getting up even earlier to ride to work feels impossible!

So, my question once again, how did you do it? I have taken a total of 15 months off from nearly all forms of physical activity and I am really feelin' it. I want to get back on my bike in the worst way, but my body keeps telling me that the extra hour of sleep I can get by driving is more important.
