I also had just about the same meal plan as yesterday. Dinner was chicken instead of meatloaf, going on the theory that the grease in the meatloaf is what triggered yesterday's bout of nausea. Guess what: the chicken didn't make me sick, in fact I had a bowl of Fritos with salsa for an evening snack with no ill effect.
We looked over the past two months and there's a pretty one-to-one connection between me feeling sick and me eating greasy foods. So while the gall bladder was fine, the cause was the same.
Lastly, the 2009 Advent Calendar has been updated.
