To the club that nobody wants to be in although it is sort of an exclusive club.
It sounds like your team has everything planned and are taking care of your authorizations, etc.
You will probably get chemo with your rads and they usually give you chemo in the beginning, middle, and the end.
Be as comfortable as you can and don't let your nerves overtake you, but I am with you this is upsetting.
Depending on your weight you should be eating all you can right n0oew and lots of it and put on some weight.
I'm not going to ask a lady her weight but if you are already sort of weighty you can ignore that.
Yes stay as active as possible as long as you can it is good for you and you will get through this and many others have
so you will too.
One thing you should do is be sure your teeth are in good shape before going into this.
You should have a recent checkup with your dentist and probably Xrays and any bad teeth repaired.
Also if you have any really bad nonrepairable teeth they should be pulled.
I am guessing your cancer team has told you about this as it's very important.
Also during treatment but especially the rest of your life after treatment you are going to have to be
very vigilant and active on your dental care.
Also after you are in treatment awhile your saliva will get very thick and you will have to rinse
your mouth out with a salt baking soda rinse and it can get bad so stay ahead of it and rinse as often as necessary, every hour, every half hour, every 15 minutes
whatever it takes but stay ahead of it and you will be ok.
Another thing you may or may not encounter during treatment is pain.
If it occurs and you are having steady pain or on a regular basis then you want to stay ahead of that also
and just take your pain meds on a regular schedule as needed like every 6 hours, or 4 hours so if
this occurs just get with you cancer team and they will help you with this.
But it is important to not wait till you are in bad pain to take meds get ahead of it.
You got this and it is not easy and there are some tough times to get through but just take it one day at a time
and before know it you will be over treatment on heading toward the rest of your life.
So this is a great place with great people so stick around and we will help you through this the best we can.
I am posting the baking soda and salt solutions below so you have them and if there is anything you need
or any questions just throw it out here on the forum.
I tell you all this not to upset or overwhelm you but to help and prepare you for this event.

And Remember NEGU (Never Ever Give Up)

  Steph Here Are Recipes

For the salt/baking soda mixes.
Rinse as often or as little as needed to deal with thick saliva even the stringy stuff.
The trick is to stay ahead of it as best you can.
There are no easy solutions but this will eventually quit.
You may find it beneficial to sleep in a recliner to keep the thick stuff out of your throat and airway.
Laying down directs it to the back of your mouth/throat area.
Even in a recliner I would wake up at times with my air cut off and had to work at getting it cleared out.

Mouth Rinse Recipes to Use During Chemotherapy

Soda and Salt Mouth Rinse

1/4 teaspoon baking soda
1/8 teaspoon salt
1 cup of warm water

Mix well until salt dissolves. Rinse your mouth gently, being careful not to swallow the mixture. Follow this with a plain water rinse to clean out any remaining salt or soda.

Soda Mouth Rinse: A Good Rinse for Before You Eat

1 teaspoon baking soda
1 cup of warm water

Mix well to dissolve the baking soda. This is a good rinse to use before and after a meal because it may soothe any mucositis pain you have, making it easier for you to eat well. Swish and spit, but don't swallow this mixture.

Saltwater Mouth Rinse

1/4 teaspoon salt
1 cup of warm water

Mix well to dissolve the salt. This saltwater rinse is close to the natural chemistry of your own saliva. This may make mouth sores feel better. Rinse well with plain water to remove excess salt.

Salt and Soda Rinse for Gummy Mouth

Some chemotherapy drugs can increase the acidity in your mouth, leading to thick saliva that can be very annoying. This rinse works well for "gummy mouth."

It seems you are preparing as best you can.
Like most new cancer patients, you are heading into a whole new thing and don't exactly know what to expect.
Here is an article from Memorial Sloan Kettering Cancer Center that covers a lot on--

Radiation Therapy to the Head and Neck

https://www.mskcc.org/cancer-care/patient-education/radiation-therapy-head-and-neck

As far as weight gain before treatment here is a comment from an H&N patient survivor--

Bulk up first

Most treatments for head and neck cancer can negatively impact both your desire and ability to consume food, so don’t skimp on meals between the time you are diagnosed and starting treatment. Common side effects can include change in or loss of taste, mouth sores, dry mouth, pain, fatigue, nausea, and vomiting, which can worsen malnutrition. I was told to gain 10 pounds before treatment but ended up losing 50 pounds over six months, going from a high of 205 to a low of 155 pounds.

And here is a recommendation from Johns Hopkins concerning oral health and checkup before starting treatment--

Importance of Seeing a Dentist Prior to Radiation Treatment for Head and Neck Cancer

Radiation treatment used during your cancer care can harm normal cells including cells in your mouth. If you go to the dentist before head and neck radiation treatment begins, you can help prevent serious mouth problems from developing after or during your radiation treatment. Side effects of radiation treatment often happen to a patient because their mouth is not healthy before the radiation treatment begins.

I only mention this again because most treatment facilities recommend it.
You are very well prepared for ongoing care and post-care but the pre-treatment dental exam is very important.
As far as the fluoride trays not many people on here had them but that is my experience from reading the listings on here.
I did not have them and have never heard anyone say on here that their team made them mandatory.
You can talk to your team about oral care and decide.
But here is a link to a downloadable Pdf guide from The University of Florida that completely covers--

So I am Wishing you the best and keep us updated-Take care-God Bless-Russ

Radiation and Chemo (if you need it) can be pretty intimidating. I'm over 2 years done with treatment, and I can still remember being scared.

Looking back, though - it was challenging, but most of what the Oncologist told me wasn't as difficult as described. Everyone is different, though - and I think they want people to be prepared for the worst.

Do you have an advocate to go with you to meetings with your Oncologist? It's really great to have someone else with you, to take notes etc. My girlfriend kept excellent track of things (like what pills did what and how often to take them). If there's someone in your life willing to help, I think it's a great idea. (People will surprise you - with offers of support!)

Another thing to monitor is your outlook. If you find the people who help you keep your spirits up, when the going gets tough - I believe things will go much better.

I suspect you're a very strong/positive person - so I think you're way ahead of me....
