Too Tired for This, Really

Have been up all night working on assorted projects; as result, head is full of medico-legal jargon and keep thinking things like "collateral estoppel generally ineffective in cases of chorioamniotis" when really need to say, "NO, you may not have chocolate frosting for breakfast." Shall spend rest of day cooking, which usually has soothing effect. Macbeth has murdered sleep; not Macbeth, obviously, but cannot seem to otherwise fix blame on anyone but myself for Leaving things Too Late.
