I have the same problem. I had my gallbladder removed on March 26, 2009. I have gone threw many test. They found out that I have acid reflux and a hiatel hernia. Maybe you should get that check just in case. I know my dr told me nothing greesy or spicy for the first few weeks after my surgery that was all i had as far as food restrictions. I still throw up and have pains and its very annoying. I hope that helped.
