The dried cracked lips are a symptom that you liver is (slightly) damaged and I would get your liver enzymes tested. If they are slightly elevated or more, I would focus on healing your liver. I had chapped lips throughout my treatment until I started to heal my liver. Going to a naturopath can also significantly improve your turnaround time because they can prescribe you specific supplements for specific ailments.
Raster do you know of anything I could take to help with my liver and get it healing?
