Full strength? ACV? or diluted? ok i have an idea, i'll try diluted and up the strength if i can take it. Please can I ask another question? is this normal for yeast to burn like this? maybe i have been diagnosed wrong? I'm pretty sure its yeast, came on after sulfur broad spectrum antibiotic. I thought the doctor did a culture, but at the time, i was stressed, nervous and miserable. I thought that was what she was doing. cindy
