Girl, like the others said - this is temporary. Surgery causes a lot of havoc on your body. Give it a week and you will lose most of it.
A perfect example of this... I was 215 when I went into the hospital to have a baby... I had my 8 lb 5 oz monster babe (via emergency c-section).... when I left the hospital (AFTER HAVING THE BABY) I was 225.

Within a week and a half... I weighed 185. Just saying... the surgery caused me to put on A LOT OF WATER WEIGHT.
