Hi NHA - Glad you found us here! ( I grew up in NH) My son had radiation only and no chemo. It was really rough for him but he's doing great now. It really is important to keep up with the calories and water every single day. You can't fall off the required amount and expect to make it up later. Ask all the questions you can think of for your doctors or for anyone here. You can get lots of ideas for questions from the main pages of this site. Check back often and let us know how you are doing.
