Top advice from red24 - you need to address your lifestyle factors it seems.
"I have been fighting yeast infections on and off for years, I want them to stop! I tried different diets, over the counter products, probiotics and nothing has worked yet." When I hear this in my clinic, I begin to inquire very much about the person's mode of living.
Are they up late at night on their computer?
What are they doing daily to relax?
Are they getting enough sleep?
Are they eating the right foods, and eating away from screens?
Do they have any stress in their lives, e.g; mother in law, boss, partner, child, etc.
Are they doing something every day that brings them some joy?
All too often I have found that a person becomes fixated on antifungals, lotions and potions, this kind of food, organic that, etc. Others want the "latest and greatest" yeast protocol. BUT - there is one thing they just don't seem to get. It's called a balanced healthy lifestyle.
If you don't get well withing 4 - 6 months of adopting the right habits, diet and supplements then you need to look a lot deeper into the WHY and start to look where you haven't started to look before. Shine the light into that dark void, there you should find some answers.
