The fact that you are not losing any more weight is a good sign. In time you'll start putting it back on when you can get more food in you. Won't be long before you have to start worrying again about eating too many glazed donuts!! Well, that will only be for a few weeks till the radiation gets going.... but there is a food break in there between all this. Take advantage of that little window of opportunity between the healing of the surgery and before radiation kicks in full bore to put on some pounds with foods that you love. Sounds like you are on track for where you are in the whole process. You can try to eat as soon as the basic healing in your mouth takes place, too soon and you may pull some stitches and such. As to the radiation type, you are a big part of the decision making process in this, combined with what the institution has to offer and the doctors opinions. While I did not have it, IMRT seems the way to go these days. If it is available, you will likely end up with more saliva in the end, and less healing time. Glad to hear you are doing well.
