I had my gallbladder taken out 2 years ago. It was supposed to be a day surgery, but I had to spend the night in the Hospital because I couldn't pee on my own. When I got home, everything I ate went right through me. I felt sick and had diarrhea, I was constantly going to the bathroom. That lasted for a day or 2, then I felt better.
I am sure that the way you are feeling, will go away soon. If it doesn't, then you should call your doctor and let him or her know what's been going on. Also stay from fat foods, will make you feel worse.
