Getting closer

Well, I have a little over a month.  Having a baby shower this Sunday for my daughter.  I have to have a tooth pulled this Wednesday.  I know I won't be able to eat after that so I am going to start testing some protein shakes.  Anyone have any good ones out there?  I have lost 7 lbs.  I am suppose to lose 13.  I wonder what will happen if I don't lose all the weight.  I have my preop scheduled for April 7.
