weigh****chers and weight loss b4 surgery.

i know alot of people use weigh****chers as a help to keep them tracking and to have something to keep up the WL.
   how many people are doing this .. I have found a DR I would like to use to have surgery ..( still getting the rejects..... but I know when its His time it will be the YES ) ...

is there anyone that has done this or continuing to do this that has any idea that might be helpful? ..OR should I just start the post op diets ( hubby has WLS 2 yrs ago ) so i remember what it was like ....

any and all suggestions would be great~~~ thanks
