My derm didn't say anything about candida in my intestines, probably because he tried to spend as little time with me as possible because Doctors have very little knowledge about EC. I figured most of this stuff out by trial and error. Overall after i took the Diflucan and used the Oxistat and got plenty of sleep, my lips kept gradually getting better and better over the course of 3 months. But I had EC for a year before this.
