Richard,
Yes, the fruity smell is a clue to candida. However, most of the clues are behavioral:
-goofy, giddy, and silly – drunken behavior
-emotional instability
-intense sugar cravings
-high self-stimulatory behavior
-high sensory seeking behavior
I am comfortable with Diflucan, although I would prefer to use botanicals or Nystatin since Diflucan can only be used for short periods of time, i.e. 2 to 4 weeks. However, it can be effective at jump starting the treatment process for candida.
I hope this helps.
