For years I suffered with frequent episodes of over active bladder, most always accompanied by headaches in the forehead region and most noticed at night. Tests for infection were always negative.
It wasn't until the last couple of years that I discovered that consuming sugar caused these flare ups. I believe that I had systemic Candida.
Now, as long as I strictly limit the amount of sugar I consume, I have no more bladder issues, headaches or body aches.
