I know what you mean by "routine" mine varies tremendously because I don't work and I never go out. Right now I am sleeping 1 1/2 hours in the morning and 2 hours at supper time (which my wife hates).
I get far less done at night because I can't do any noisy activities. I guess I have not had anything like a normal routine in about 13 years.

Hmm, you'd think I would have figured out how to work around this by now.
