Day 6 - Which weight would you use?

Well it is Day 6 since my VSG and I'm doing okay.  Having problems finding a protein drink I can tolerate.  OMG they are horrible.  They are either too sweet, too thick, or just plain taste bad.

I'm weak but getting around pretty good. 

Not sure what weight I should count from.  On 7/1/11 when I started prep for the surgery I weighed 252, but by the day of the actually surgery I weighed 246.  I've actually only lost 11 lbs since the surgery.  What weight would you use?
