Slept slightly better, with 50mg of diphenhydramine. Don't expect that to work tonight, but will try it anyway.
Definitely displaying too much competence at work. Got more work added to my queue already. The more I dig into this code bade, the more of it I want to rewrite. I've spent the past two work days refactoring the authentication system. Because I am clearly insane.
Depending how I feel in the morning, I'm thinking of trying bussing from a P&R.
