Kyle, hello and good luck for starters. I too had tonsil cancer. I made it through without a peg. I had rad and chemo together. I was about 210 and pretty muscular I am now about 175 and can only lift what my wife lifted at the gym yesterday. I had a couple of struggles with nausea that had us concerned. Very rapid weight loss. I also had to have fluids the last two weeks of treatment and the week following. I have not had a solid meal in 2 1/2 months. I have started to eat small servings of soups at the end of the day. I actually am feeling pretty good though, and my docs are extremely pleased. That being said there was a point that had I not had a break in the nausea I would have probably had to get the peg during treatment. That was scarier for me for the obvious reasons of possible infections if your blood counts are low. I was lucky and maybe new meds are helping some of us make it without pegs. I don't know but I think if I had to do it over I would get the tube just in case I hade to use it. If I didn't have to use it I guess they would just remove it afterwards. I'm glad I made it but about mid way through I was extremely concerned. I think what made me not get one was that I had an iron stomach. I don't think I had ever been nauseous. When I got that way I was miserable and had absolutely no desire to eat. Thank goodness for Zofran. I took it and My nausea disappeared. If I had the tendancy to be nauseous I would absolutely get one. Good luck with your decision.
