Been there done that. A nurse at Mayo Clinic suggested I rinse my mouth with !/2 teaspoon baking soda and 1\4 teaspoons salt with warm water. Never got mouth sores but throwing up was frequent daily for 5-10 days. Wore baseball hat with hair loss. It comes back. Maybe not same but mine was a little curly. Stick with Dr. You like believe me it’s worth it.
Prayers and good luck.

My chemo hasn’t started yet, but I’ve been prescribed meds to combat nausea. Decamethasone 2x the day before chemo and 2 a day for 3 days starting the day after chemo. Also ondansetron and prochlorperazine as needed for nausea. My chemo
starts Apr 26, so no idea what to expect. I’ve read that ice chips during chemo infusion helps reduce mouth sores, but I have no experience with that. Good luck. I’m grateful for this group.

Hi Sandy,
I was diagnosed with NSCLC one year before you(Feb 2022). Mine was stage 3B. I couldn't have surgery because it had spread from the lung tumor into two lymph nodes, one Hilar node and one Mediastinal node. But I did have radiation and chemo similar to your plan. The radiation I had was proton radiation though instead of photon radiation(x-rays). If that is an option for you I definitely would recommend it.
I had 6 weeks of radiation 5 days per week and 6 weeks of chemo 1 day per week over the same 6 week period. My chemo was same as yours, Carboplatin and Paclitaxel. You have to infuse the Paclitaxel first before the Carboplatin but they will know that. The first time I had a bad reaction immediately to the Paclitaxel. They had to stop it and give me some other meds and wait for 45 minutes so I could tolerate it and then it proceeded OK after that. The meds were just stuff like benadryl, famotidine, some steroid and Tylenol. For the following weeks they would just give me that stuff first and the whole series went well.
For side effects I was pretty lucky. They gave me prescriptions for anti-nausea drugs, Odansetron and Prochlorperazine, but I did not take any since I didn't get nauseated enough. They gave me quite a few sample bottles of Boost and Ensure in case I had trouble swallowing because of the esophagus reaction but I didn't have very much trouble with that either. I was able to eat chew-food the whole time. I did have fatigue from the chemo and a vague feeling that I wasn't "normal" during the whole six weeks and beyond but that fades away.
I did get an area of "sunburn" on my back in the later weeks of the radiation treatment since about two thirds of my radiation came in through the back and one third through the front. I couldn't reach it well but the techs here would put lotion on it for me so that wasn't too bad either and it faded over a few weeks after the radiation was over.
I did not lose my hair. I might have had more thinning but it was thinning before anyhow. It was impossible to tell if the thinning trajectory changed at all. I didn't try doing anything about hair so I am no help there.
I just finished one year of immunotherapy. Just a one hour infusion every four weeks. This drug was targeting my specific cancer genetic mutation and was much easier to tolerate than chemo. Just some fatigue which I hope will start fading away pretty soon.
During this last year I did lose my gallbladder but that was probably completely unrelated to the cancer or treatment. I also lost most or all of my thyroid gland function and that was caused by my immunotherapy drug. This happens to about 20 percent of patients taking that drug and I was one of them. In the big picture that is a small price to pay for the cancer killing protection of the immunotherapy.
Now I am all done with therapy and just have followup CT scans. These followup CT scans become extremely important to cancer patients. That is the only way you learn what good and what bad is going on inside you.
