I remember reading a story a long time ago about this guy who was out in the desert and was going through the different stages of dehydration. The story was written for the purpose of describing those different stages of dehydration so a person could recognize it and do something about it. Anyway, the first stage of dehydration, according to the story was chapped lips. I think that we, in American culture, tend to think that all our cures have to be bought at a store. We tend to go out and buy pills and medications to fix what ails us instead of actually addressing the problems at their sources.
Water is free and dehydration has a cheap cure.
So that's my slant on the chapped lips thing. Yes, I still use a little bit of the Neutrogena stuff, mainly because I sleep with my mouth open and my lips get dried out when I do. But one tube lasts me about a year. Most often just drinking water keeps me in pretty good shape. And by the way, just to give you a general idea of how much water I'm talking about, I think I drink about a gallon of water each day.
