Guess my weight!

This afternoon I will finally get rid of my tonsils. I'll also lose my uvula, part of the back of my tongue. The doctors will also drill a small hole in my jaw and pull my tongue muscles forward.

All this means I won't be able to eat solid food for a while. Possibly a week. I've already had to fast for 14 hours, so my behemoth (for a runner) frame is going to shrink a bit. The question- how much?

During my pre-surgical visit, I weighed 181.3- a lot, I know. I have a followup visit on the 14th. My question to you is- how much will I weigh then?
