There is an awful lot of myths and disinformation around with regards to Cephalotus. Generally, I use the appearance of the plant pitchers as an indicator to its health. If the pitchers have a shine to them, then they are generally OK. If they start to look dull and limp, they are not. The latter generally indicates that the plant is either too dry (humidity, soil or both) or has been kept too wet and the roots have rotted!
