ER Gallbladder?!

So at the ER, they told me it was gallstones and to see my surgeon the following day. So the next say I called and couldn't get an appointment so I went in Thursday and Dr. felt around and said, "okay, lets get it out. I was confused. He said "what time works tomorrow". Um no time! My work Christmas party is the next day so I literally didn't want to. I asked if we can do it Wednesday December 7th but he said he'd feel better if we did it Monday the 5th. So it's scheduled. Monday. I need to shower with the same soap as for VSG. I'm going to work from home Tuesday, Wednesday and probably Thursday too so that's nice that that's an option. I am very nervous that I won't lost weight after the surgery...
