i think the doctor is right that it is dehydration. i cured my ec of 18 years by stopping licking and using only water all day to moisturize them. i dont recommend using any products because none ever worked or helped me. the only thing that worked was long soakings in water and leaving them alone. alot of people have the mindset that saliva is good for the lips because it feels good. soaking in water, which can be done simply with a technique when drinking, will cause the scab to fall off naturally without biting it or whatever. oh and btw, there are quite a number of trolls on this site who choose to try and discredit my every post, so just be forewarned and take my information at your will.
