Hello. I feel your pain
I have the same problem. I have CFS/Fibromyalgia/Lyme and if I don't have chap stick I start freaking out! I have tired a bunch of different kinds. Most of them suck. There is one that is hands down the best of the best. Coming from a fellow chapstick addict your gonna have to trust me! You will LOVE IT!
This is the BEST stuff!!!
Natural Ice
You use to be able to buy it in wallmart. They no longer carry it and I have to buy it online.

Second to that is Burts Bees Lip Balm
You can buy it in most stores like wallmart. I would try the Natural Ice thought.
