Hi, Mike, lots of good tips above -mine are short and sweet- use your peg to get as many calories and as much hydration daily as you can before you start radiation. Use this time to experiment with which peg food nutrients your stomach will tolerate and which technique works best. You want to stay ahead of the game here. At the end of any peg feeding, flush the tube with 6 to 8 oz of plain water and keep the area around it clean. Amy in the Ozarks
