I agree with Christine with respect to the IV hydration, especially at this point.
Also, be sure to stay on top of your pain levels so as not to let them get out of control. I had a palliative care team taking care of me. They help to manage a cancer patient's pain, not just end of life issues.
Best wishes. I know how hard it is and I am so sorry that you are there right now. Just remember, this will save your life, even though it feels like it may be killing you at the moment.
You will be in my thoughts. If you've made it this far without a PEG, then I applaud you. I think I had one place during the third week.
In good health,
Kerri
