Same here, check water daily, spot check.
I examine them regular, check their eyes, nose and entire bodies looking for unusual bits ie mites, weird scales, tail tips.
Once you've had your snake a while you get used to the behaviour, for example i have 3 corns, all behave completely different but all "normal" for them. My male Carolina never sleeps i'm positive, especially this time of year, whereas my female Lavender and Male Snow only mooch around when hungry or in the wee hours of the morning.
