I occasionally suffer from sweaty palms, mostly when I am drunk or at work and trying to play pool or darts. More often I suffer from sweaty feet, in the morning when I can't sleep, i put socks on because they stick to everything. I normally attribute it to an imbalance, and since it always goes away it
always seem to be recoverable, but that is just me. Same thing with the dry lip thing, I come to realise that specifically is to do with perhaps eating not enough or too much of something.
