Hello, Eagle! Welcome aboard, but sorry to hear about your diagnosis. I think you'll find just about everything you could ever possibly want to know about OC here. There's some incredibly kind and knowledgeable folks here that will respond with sincerity and above all-EXPERIENCE. There is a wealth of info on the other pages and you can do searches in this forum to see what others have experienced with similar issues.
My own chemo/rad (round 1) was noteworthy in that no, not EVERYBODY gets sick as a dog on chemo (not so true THIS time, however); and yes, I SHOULD have gotten the peg BEFORE radiation but I'm stubborn. One of my good 'taurean' qualities, but by the end of rad tx I was down 55 lbs and I've got a picture (somewhere) of me that barely looks HUMAN. I'm a 5'8"/160lb man so this was kindof radical and they did end up putting one in. I actually liked it as I tend to be the "busy beaver" and found it delightful that I was saving so much time by not having to fix meals! :-)
Radiation can be a bear. But you can bear it. My discomfort started with the very first treatment (VERY unusual) but was 'tolerable' (boy is THAT a subjective word for a constantly changing/evolving state of mind) for the most part. Believe it or not, you WILL get through it. You're a heck of a lot stronger than you've ever given yourself credit for and you'll find that what is scary as hell from this end can, and will be successfully done when you come out the other end. You'll be helping others to go through similar situations in no time; and THAT'S a good feeling.
Please post as often as you want with WHATEVER is on your mind-you'll get some real support here, my friend. You're NOT alone, no matter what you're probably feeling right now. We've been there and can help you go there, too.
Stay strong and keep us posted
Gordon
