Same here man. I'm just following my strict diet - just the same as you had, because I have stomach inflammation, Hiatus Hernia and liver problems but I see no improvements at all. Lips are peeling all the time. The only thing that gives me any relief is this http://leki-opinie.pl/wp-content/uploads/Ma%C5%9B%C4%87-ochronna-z-witamin%C4...
It's just a protective cream with vitamin A. It's nothing like tretinoin or retin-a. It's safe to use it. I bet you can find such thing in your countries.
By relief I mean - I don't have huge HARD crusts. Just dry lips peeling all the time. That's it for now :/
