I thought I could force myself to eat even if I didn't have an appetite, not true. My wife had to take the long way when I went for radiation treatment because I couldn't stand the smell of the cafeteria. I eventually had a feeding tube put in so I would stop losing weight. It's pretty easy to pour in the reccomended number of cans whether you want to eat or not. MD Anderson has a good nutrition department. If you can see them, they might offer some suggestions. Keep up the good fight and find something that you can eat to maintain some energy.
Mike: In 1975 I went thru 6 1/2 wks of upper body radiation. Had to go down an elevator to get to radiation site. It just happen to be in the same area as the caffateria. The dish washer soap smell just floored me. I would take a big breath when entering elavator and hold it until we got thru the glass doors of the radiation area. To this day, there are times when I enter a resturant and the smell how unnoticeable to others still makes my stomach quessy. Hang in there there is lite at the end of the tunnel. Try eating small chocolate or other flavor milk shakes. A couple of mouthful worked in settling my nause. Good Luck and God Bless.
