When do you weigh in & why?

I asked once about weigh-in rituals and superstitions.* Now how about weigh-in day and time?* And why?
*
I weigh in on Thursday morning, first thing.* Now the reason I weigh in on Thursday is, if I'm gonna cheat during the week, it will usually be on the weekend, and weighing in on Thursday gives me time to recover from anything I really shouldn't have eaten.* The reason I weigh first thing in the morning is I don't want to have any food from that day 'weighing me down'.* So, I will not eat or drink a single mouthful before I weigh.
