gaattagirl;
I was told the metal taste of the food was due to the chemo (Cisplatin) in my case, but the radiation soon remedied that as nothing had any taste at all. The food intake will continue to slow as the mouth sores and pain continue to ramp up. Use the medications and if you're not getting what you need ask your doctors for them. Karen is correct about the patches and liquid pain meds. I found the patches (fentanyl) to be very accomodating.

Since you have a PEG tube, use it. Use it often and maintain your energy and weight as well as you can for as long as you can. I know that is easier said than done, but I believe the better your focus is on these few things the more it will help your recovery time. I fought using the tube until it finally became my allie. (finished my rad/chemo 6 weeks ago and 2 weeks prior to 2 weeks after treatment I couldn't hardly get a small swallow of water down my throat)
Even when you finish treatments the after effects you've read so many on this site speak of continues, and when you are eating again it's still tough to get enough nourishment, so train yourself to use the tube! Lastly, I don't want to preach but do away with the cigarettes however you have to. You are in a fight for your life and they can't be helping at this point. Try that pill you speak of if it will help.

As you stated, you have God on your side, and you have a positive attitude. Some of these side effects are a small, (hopefully most being temporary) price to pay for your life. Hang in there, it does get better.
