I recently posted a picture on my instagram of a pile of Salivix boxes on my bed. Salivix are some sweets that help stimulate saliva and I think they're actually recommended for cancer patients. No one had heard of them, but plenty of people were struggling along with the dry mouth side effect of medication.
My aim with this blog has always been to be completely honest with my readers, so, without being too graphic, my skin has been so dry to the point where I have patted my face with a towel after a bath, applying barely any pressure, and my skin has literally bled from my forehead onto the towel. I know dry skin.
