to me it doesn't make sense that you are worried about saliva drying out your lips, when you have dry crusty crap on your lips. you said you leave them alone for days and you tried leaving them alone for 6 weeks which I assume you did not lick them at all and whatever else like not touching water to them either? ive been licking my lips for years now and nibbling the crud off and it works and I will never go back to trying to let them heal because I am normal like everyone else. i had a scab on my cheek that healed fully in 7 days but you think your lip crusts are going to take 6 weeks? i wouldn't worry about saliva drying your lips out if the alternative is dry crusts. you said you leave them alone which i take you don't lick your lips. i know this is the problem. if you have had this for 2 1/2 years why don't you just try what i said for a month, if anything you will feel relieved and happy that you look normal.
