Re: sirpies!
I was never a lip biter or picker.
I used to use chapsticks for many years (I remember using it while I was in highschool; my mom and my brothers also used it). I did not have chapped lips, but they always felt just a little dry when not using anything on them (the addiction has probably been caused by using those for so long). But when not using anything on them, my lips never got chopped.
I didn't get EC while on the snowboard vacation. It was a few months after that, so I doubt it had anything to do with it.
A while before the EC started, I tried to go cold turkey from lip balms. It didn't really go too well without anything. I would use honey at night sometimes, but eventually, I bought a can of Vaseline and used that. Some time after that, the EC started.
When I saw the white build up for the first time, I removed it using tweezers, but stopped a day or so after that, for the most part, and saw my first derm.
