My doctors did not give me a choice on the PEG tube---I was getting one. I weighed less than 120lbs, so I guess they figured I couldn't afford to lose ANY weight. I continued to eat solid food throughout my treatment, so I didn't need the PEG tube for calories, but it sure was convenient for fluids. The day was not over until the allotted number of bottles of water either made it down my throat or down my tube.I could have made it without the tube(i only lost 4 lbs) and I hate the scar it left, BUT---you never know how your body will react in the final weeks. The PEG tube made staying hydrated no problem.Good luck to you, think good thoughts!
