Strong body smells and bad breath are often caused by emotional issues of wanting to isolate oneself. In some cases it's about keeping somebody away out of your life. \
I knew a young MD whose breath would wilt flowers. When I worked with him, it came out that he was unsure of his abilities and subconsciously didn't want patients for that reason. When he heard this, he had his AHA moment and his breath within a few hours was much improved.
A woman had the breath that could make a hog farmer's eye's water. Her husband had been cheating on her and she wanted him far away and out of her life. But her financial situation at the time left her stuck. But her breath did improve and eventually the couple reconciled. I was told it took months to get the smell out of the bedroom.
So the first question is, who is it that you want to distance yourself from?
