Hi. My name is Redtail, and I’m a recovered Carmex addict. <Hi Redtail!>
Seriously, I was physically addicted to Carmex - not any bizzaro weird or mental stuff, just that if I didn’t re-apply the stuff at least a dozen times daily, my lips HURT! Getting that Carmex monkey off my back took several weeks of burning, stinging, aching lips. Then I was dumb enough to start again!
But I’m proud to report that I’ve been clean and dry for many years now. 
I’ve never really had problems with any other brands of lipbalm, just the evil Carmex. But then again, that was the only kind I used, so I can’t really compare.
The ‘addictive power’ of Carmex was well-known amongst all of my friends. Well, ok, we didn’t make up freakazoid theories about them putting in addictive ingredients (except as a laugh), but we all had the same problem with not being able to stop because it hurt so much to go without. We just figured the stuff dried out your lips really badly, while keeping them gunked up enough that you didn’t realize it until you stopped. I have a good friend that still carries Carmex everywhere he goes, just as I did 15-20 years ago. I quit; he didn’t and has been using Carmex daily for all of that time.
I would guess that the phenomenon is the same sort of dry-skin problem that many people experience from excessive exposure to detergent or other chemicals (aka “dishwashing hands”).
So no, my problem was NOT “obsessive behavior”, thank you very much. It was a purely physical problem. The longer you used Carmex, the more often you used it, and the longer it took to quit hurting when you stopped using it.
As far as ‘devaluing’ the word addiction, the online dictionaries state:
addiction n
1: being abnormally dependent on something that is psychologically or physically habit-forming
1: The quality or condition of being addicted
2: Compulsive physiological need for a habit-forming substance
Since it was physically habit-forming and I was abnormally dependent, I’d say it qualified as an addiction. Was it a serious, life-threatening addiction? No, of course not. Neither is my caffeine addiction, my addiction to the written word, nor (shall I say it?) my addiction to SDMB ;). Was it so addictive that I couldn’t stop? No, but I did have withdrawal symptoms.
The best cure I’ve found for chapped lips is to stay hydrated (I used to drink NO water at all). If your lips start chapping, you can gently scrub them with a soft toothbrush or wet washcloth to remove the dried-out skin before it peels. (IME, when it peels off by itself, it tends to take more ‘good’ skin with it and compound the whole problem.) But then again, there are just times (e.g., deep winter or post-sun frolic) when they’re just a-gonna be chapped. Pure aloe vera (I use the bottled gel due to my complete black thumb) seems to help chapped skin no matter where on my body it is.
But y’know, that heroin line from the Carmex guy was almost funny enough to make me consider giving them my money again. Anyone who would answer like that is someone I could get along with.
I haven’t read the lipbalm website - is it actually amusing enough to be worth it, or is it just another website by a bunch of clueless idjits with a ‘cause’?
