Thanks for the responses. I'm still not sure what caused the problem the other night. At Outback, I ordered off the gluten free menu- I had the lobster tail- steamed, a baked potato with butter, and a salad- no croutons of course, with oil and vinegar as the dressing. I had this at about 5pm. It wasn't until around 1am that I had the cheese and olives (I work nights so I don't get to bed until about 5am). The cheese was a brand new package and the olives were in a freshly opened can. I started feeling sick around 2:30am. I stayed up feeling miserable until about 6am, woke up at 12pm and felt better. So I guess the only thing I can think of is cross contamination at the restraunt. I'm scared to eat anywhere and anything right now!
