When I had radiation the nurses presented me with a bucket to keep in my car. I had to drive about 20 miles over bumpy roads and would have to pull over or throw up in the driveway. Often I never made it out of the center. Once I stopped the drug (thankfully forgot the name, but it's in my signature) that was to protect my saliva glands, it got better. I was on 4 anti-nausea meds, but I think not drinking enough while on that drug was the problem. I still continued to feel sick as soon as I entered the cancer center. It had a hospital smell that made me want to gag. Putting a dab of peppermint oil on my wrist to smell seemed to help. I also would vomit when I drank specific drinks that I consumed a lot of early in my treatment. Now when I go to the cancer center, I take a deep breath as a reminder of how far I have come. I also can drink those drinks that triggered nausea. The good news is, only 1/3 of my saliva was lost and I can manage fine without it.
