Reading an older article - http://www.straightdope.com/classics/a981225.html , and I’d been told that while the substances in lip balm aren’t addictive the way drugs are, but that because it provides the moisture to one’s lips, the lips/mouth stop feeling the need to moisturize themselves. So one adds more chapstick. So the natural moisture doesn’t come through. And so on.
It happened to me for awhile. The only cure is to quit cold-turkey.
