Erik,
I hate to sound like the odd man out, but, I was nauseas AND vomitted throughout every day during the chemo and radiation. It started when the hooked up the 5FU the second day of chemo and I believe it ended something like 9 weeks later (or beyond). I remember the room spinning between the calls to my pharmacist dad asking him what else he suggested I ask the doctors for. We tried them all and nothing ever changed. A friend gave me pot and it helped in a matter of seconds but I can't recommend breaking the law and using something that is a potential carcinagen as well. When I had the ethyol shot to help protect the salivary glands, it made me even sicker and pot was the only thing that helped me from barfing up my intestines. I even had a bucket I carried to daily radiation and everyone was beginning to giggle as soon as I walked in, wondering when I would dash the restroom the first time. I had to remind the radiation techs to be sure and turn the volume up in the room so they could hear me gurgle so I wouldn't choke on my own vomit. It was very humorous to everyone...except me. My wife was just hysterical the other day, reminding me how "cute" I was on all fours praying to the throne in the "reading room".
Hang in there, for some it is worse, but it always passes. You are almost home...
If you have a mediport or central access line, daily fluid is not bad and be sure they monitor your creatinine. Vomitting will surely dehydrate you and that only makes the chemo much harder to tolerate. Like Robert, I had 3 bags of fluid a day from week 3 until 2 weeks post treatment. After returning to work, I had two bags at night for 3 months. If you have blood pressure checking capabilities, check it sitting and standing. Ideally, it should be the same but a wide spread is a quick indication of dehydration. The body is 60%-80% fluid, depending on the part(s) and dehydration will exacerbate mucositis, stomatitis, digestive issues, sores, dry mouth, etc.
I, too, was mentally down during all this and until I got the rest of the family on anti-depressants, it was almost intolerable!
I still remember talking with an oncology psychiatrist and she asked me if I needed anything for depression and I told her to give me a few weeks to see how the rest of the family responded to their scripts!
