This combo is not likely to cause a loss of appetite. Anything can happen on any medication, but with your combo, not likely, so it is probably psychological. Is there some food you can eat without working up an appetite - yogurt, apple sauce, oatmeal, a peanut butter sandwich, spooning peanut butter from the jar? You need some protein and if you are not getting it because you are not hungry, it is not good. Not good at all. Even something small - a yogurt here and a spoonful of PB there - would help you.
