Wendy, its very common to lose your appetite when going thru rads. All the issues you wrote about are normal and have happened to almost every single patient who has gone thru rads for OC. When food doesnt taste good or the smell of it bothers you that plays a part in having an appetite. I dont know if loss of appetite is from the patch or not. Id suggest reading the fine print pamphlet that comes in the box or asking the doc. Id also ask your doc about things that can help to stimulate your appetite. In my opinion, its all part of treatments and recovery and in time this will slowly change. The burning you experience is very uncomfortable, milk or yogurt can help with lessening the burning mouth. Avoid spices helps too. Hang in there, you are almost to the turning point where you will begin to feel a little better.

Best wishes with a speedy recovery!!!
