Dry mouth is definitely a symptom, you'll probably find it doesn't happen everyday but there will be a sequence of symptoms. Last Wednesday my feet really hurt in my shoes, water retention was making them swell, Thursday I must have peed 4 times in 5 hours, normally I pee once in a 7 hour shift. my sense of smell heightens and everything smells of dogshit. This might be TMI but I also get a really painful Vagina, the kind of feeling you get when you've been shagging all night (I wish)

One thing to be aware of is that diabetes can rear it's head even if you are not overweight and also thyroid function can be compromised, most GPs will actaully check for diabetes around this age but the thyroid tests are pretty crap. I think the parameters they use to diagnose Hashimotos are wrong personally.
Also my hands can look ancient sometimes, all dried out and wrinkly even when I make sure I drink plenty of water and moisturise then after a week they are fine again.
