Welcome Jim-
So sorry you had the need to find us. The others are right - your dads cancer was caught early and there is a good chance for a cure. I was unfortunately not diagnosed until I was Stage 4; told I would be here for a year; just passed my 3 1/2 year mark and feeling great.
Chemos differ with different people. Yesterday was my 70th chemo and I have NEVER thrown up. I only get Kytril in my IV, nothing additional. I have recently developed some constipation and I like to take senna tea. You can find it at Health food stores. One warning - experiment with it - never start out with a tea bag and the recommended steeping time - I did that and found it to be the gift that kept on giving!!! Don't you just love a web site where people talk about bowel habits??? Or their log jams as Ned said!!!
As others have said, once your dad starts on chemo and hopefully gets over the fears of it, he will start to feel better. My first chemo, my girlfriend told me I looked like a deer caught in the headlights. And guess what, he is ALLOWED to be nervous and scared - this is big time stuff.
Let us know how he does. Your dad is lucky to have you by his side
