Hard to quit when lips are constantly chapped

As I'm writing this it has been 23 days since I had a full blown picking lips session. This is the longest I've ever lasted and have been dealing with this along with an extreme chapstick addiction for about 15 years.

Just over a month ago I quit chapstick cold turkey to see if they were drying up my lips. I've switched my toothpaste and now rely on Vasaline once in the morning and once before bed.

I thought my lips would get better over time, but every afternoon I find them chapped and peeling and it takes so much strength not to just rip the skin off. In the last few days I've had to use Vasaline about 5 times in the day as it lasts about 20 mins.

I know it's still early days and I'll probably have to go back to using products more frequently but I can't believe how much my lips chap so easily. I drink throughout the day, but maybe it's the cold weather making this worse? Or maybe 15 years worth of chapstick and picking has just permanently messed up my lips...
