On a positive note you are nearly there you can see there are only small areas to repair themselves, I imagine if you leave the lips alone these areas will crust over and become repaired. You are at a similar stage to me actually.
I would recommend you dont steam, you eat healthy, dont drink, dont smoke, exercise and leave your lips alone as much as is physically possible - drink through straws, wash your face with a flannel etc etc
AND relax and be happy!!!! because you are nearly at the end my friend!!!
