My doctor never really asked me if I wanted a peg tube or not.  He said he would be putting it in pre-treatment.  Sounded like standard operating procedure for him.  I am thankful I did have it.  After the 2nd round of chemo at the end of week 5 I couldn't swallow anything, and I had no appetite at all.  With the peg I was able to maintain a 3,000 calorie a day diet with the carnation instant breakfast vhc drinks.  I believe with the right nutrition I was able to heal better.  Over this past weekend, at 9 months post treatment, I ran my first 5K (3.1 miles) race, which was also my first race after treatment.
