Welcome, Damn
HPV got me 1 1/2 years ago. I too was in great shape, ran lots of 10Ks. As to what you have to look forward too. Everyone is different. Some sail right thru others struggle right out of the gate. Being in good health should help, but rads and cisplatin may not care what shape you are in. I struggled week 1 then weeks 4-12. The two after treatment were down right awful. As you probably heard by now, getting food and water in you is kind of important. It will become your biggest challange. 2500 cals is tough when your healthy, Now you have to do this when you feel like you are swollowing razor blades and there a 50-50 chance it might come right back up and you will have to do it again. Some of us had to get peg tubes because feeding was just that difficult. Every day brings new challages and I spent most of my time (8 hous per day) tring to get food in me.
My advice to people is aways take advantage of the time you have right now to get as much stuff done as you can. I am thinking cars, garage, yard work, home repair. Simple things like taking out the garbage might become difficult. Get help you may need it. Always have a back plan to get your butt to treatment. Put your game face on, you have been drafted, and the best way out is thru the IMRT machine.
The good news 4 weeks post treatment life starts to get better. Stick with us thru treatment, you will be glad you did. Post as often as you like and ask lots of questions. For me it really pulled me thru the rough points.
