I have not been in this situation but would imagine you will be ok. May be get some protein bars, small ones, and some gelatein from the band buddies site, this has 20 grams of protein in it. (A medical jelly) there is more than one way of getting protein into yourself. Everyone is different on the food they can eat. I at least have one protein bar, small 100 cals and 10g protein and a gelatein 20g prtotein and 60 cals every day. I do not get hungry and found that I was not having enough protein and was losing muscle mass. So you can add to your intake until you can eat it with normal food. It is just a temporary phase.
The protein bars i use are Protein fx, you can get them from the supermarket or the health food shop.
I am sure you will be able to adapt to your body's needs.
