I have no experience with Diflucan, but I do with another drug nilstat, and the effects you're getting seem short term, it sounds like die-off and it's working.
I'd stay the course with whoever is helping you. It's encouraging that you're going on natural anti-fungals after.
However, I wouldn't be satisfied with this, especially if you continue on drugs every once in a while (most drugs are harmful long term). Keep looking.
I've posted some protocols in my other messages that could help, but I won't spam the board with them.
