I have a problem: six months ago, I gave up caffeine. Since then, my body has insisted on having eight hours sleep a night instead of five or six. The change in my health is enough that I'm not going back, but I really miss those hours. Specifically, between ten and midnight I used to get a lot of reading and writing done, but nowadays by ten I can barely keep my eyes open.

I've tried quite a few ways of cutting back my time expenditures, and I do seem to have gained some time back, but it's fifteen minutes here and ten minutes there. I can't seem to get back the time I really want-- a couple of hours when the house is quiet and still, and I'm feeling peaceful, reflective and productive.

Has anybody been there and hacked that?
