Have you tried xylimelts at night? 
Cant help with sunscreen as I tend to use whatever is cheapest. 

Yep I do use them. Again I find I have to swill out the liquid they leave and they seem to upset my guts. Thanks for the reply.

Aldi and Lidl factor 50 spray....cheap and very effective

Thank you

Dry mouth - Have you tried acupuncture?

I finished treatment for nasopharyngeal cancer in late June. I think it’s helping me to combat my side effects. I also have Chinese medicine to complement my treatment.

Another thing you could try is:

Biotne Dry Mouth Mouthwash, Moisturising & Alcohol Free Oral Wash, 500 ml - I am not sure it’s helping me that much but it has quite a few good reviews on Amazon.

My Chinese doctor suggested that I could chew American Ginseng. I haven’t got that yet so I don’t know how effective it will be.

Ah, yes. Some people are sensitive to xylitol

I'll second VVN's suggestion re acupuncture. It did help me. I have a couple of entries in my blog about it

Thank you for your sugestion, acupuncture has been mentioned to me I'll investigate. Not tried the mouth wash I'll also look into that , Thank you.

Thank you for the reply. I'll look into acupuncture. 

Before I had radiotherapy, I used NIVEA Sun Sensitive Immediate Protect Allergy Sun Spray SPF50+ (200 ml) on my face, neck, and body. I think it was the best product I’ve used, especially as I also have eczema. If I was wearing makeup, I’d use IT Cosmetics Your Skin But Better CC+ Cream SPF50 (32 ml) instead.

After radiotherapy, I started looking for the best sunscreen for my face and neck because I’m still healing from burns and hyperpigmentation. From what I found, a lot of sunscreens contain Alcohol Denat, which can cause redness and irritation, not ideal when your skin is already sensitive.

Now I use Dr V INZINCABLE SPF50 for my face and neck. It doesn’t contain Alcohol Denat, and even though it’s quite pricey, I think it works well for me.

I also use MOOGOO Udder Cream to moisturise my face and neck.

Hope this helps.

Thank you. That's useful info. I am concerned that some sun protection isn't very good and I'm trying to get recommendations as I go out everyday walking and I'm finding my face and neck are suffering despite using a suncream, so thanks I'll check out your suggestion.
