Sometimes it takes months to clear this up, even using both over the counter medications plus bouts of the presciption type. You must at the same time consume no sugar - no juices - no refined carbs - low glycemic-index foods and fruits - eat like a diabetic SHOULD eat.

And, in addition to that, use high quality probiotics.

And get tested for food sensitivities, or just get off gluten and dairy for 6 months.

I am not a doctor. This is just from experience.
