Buy an aloe plant and use the sticky gel inside the leaves for your skin and hair. It works wonders and the smell goes away so don't worry about that. It's also good for reducing wrinkles. There's loads of info online and at youtube showing detailed ways of using the aloe. In my experience, the commercial aloe gels have too many additional chems added to them.
Dry mouth leads to more cavities, gingivitis, and overall tooth and gum decay. Biotene has mouthwash, gels and sprays to help with dry mouth. I've always used just a little bit of vaseline on the inside of my nose to help with the dryness that causes my bloody noses.
I play brain games or memory games to keep my mind sharp. Games actually do stimulate your brain, they aren't just for fun.
last but not least, medicinal marijuana (where legal) can help reduce your anxiety (sativas promote social behavior and stimulate your creative mind but indicas will bring you down, reduce your desire to interact but will aid in sleep and reduce pain) but it will also cause your mouth to be dry so keep some sugar free hard candies or that Biotene mouth gel handy.
Good luck to you
