Gallbladder surgery

I didn’t know it at the time, but I had a gallbladder attack this past Friday. I went to the ER because it was 1am and I didn’t know what was happening to me. Looking back on it, this would be my second gallbladder attack. I get extremely bad stomach aches so I thought the first one was just another stomach ache. Now I have to have surgery to get my gallbladder out and I was wondering if any of you have had that surgery? I know it’s a common surgery, but I’m nervous being that it’s my first surgery like this. Is the pain afterwards bad? Are there any foods you can’t eat?
