My wife jumped on the paleo bandwagon...and has had a hard time of it for the last two/three weeks. She has some nausea most of the time, which gets worse when she eats. Meat (any kind) seems to make it worse. After eating meat (20 minutes or so) she threw up three days in a row. She has been able to keep some chicken down the last couple of days, and fruits and veggies don't seem to specifically give her trouble. She has also completely lost her appetite.

She's not eating anything she didn't eat before, just cut out sugars/grains/beans/etc. We don't think she has a virus, but we're about stumped. Does anybody have any suggestions/ideas?

Getting desperate...
