Follow-Up:
I have finally found something that helps me. Came across an article praising the wonders of Baking soda. Supposed to be good for digestion, etc. by balancing your PH level. So I stirred 1/2 tsp in 1/4 cup of water. Stir good and drink fast before it settles on the bottom. Also take between meals. I was surprised that in a couple of hours my lips were soft and moist for the 1st time in 2 years. I have to assume that my body PH is so acidic that it's literally burning the skin off of my lips. I usually take it after my mid-morning coffee (which starts my lips burning again) and before I go to bed at night. Instead of applying vaseline every 15-30 minutes during the day, I only have to use it once every couple of hours. Right now I am using a non-sodium bicarbnate called Tri-salts. I'm interested to know if this works for anyone else. Good luck.
