So exhausted I can't see straight. P is being kind of pathetic at home, whining, licking back obsessively, very frisky when out on walk, has extremely good appetite, steak has been suggested as cure for what ails him, may go get one once I've had a chance to rest a bit. May need to take him to vet after all, no matter how much he hates it.

Sleep deprivation has been making my mind race, think it may be making me temporarily more effective, may be illusory, can't last.
