Tomorrow will make 4 weeks since I began my 2 week liquid pre op, surgery was Dec 19th. I lost 14 pounds before surgery and have only lost 5 pounds since the 19th for a total of 19 pounds. I have been up and moving since day one and making sure I get at least 60 grams of protein in protein shakes and 48 oz of water. I worried that this surgery wouldn't work for me and beginning to think its true.
