If you want to get rid of the H Pylori then just drink 1 ounce of a good brand of colloidal silver(nanoparticles) 3 times a day well away from meals. See this.
My guess is that it was because of taking all those anti-biotics that your doctor recommended that caused the massive imbalance and caused your candida to dominate in your body as it has done.
I can't really describe here what you must do to cure yoursef of this horrible disease -- not enough room. I had systemic candida myself 8 yrs ago and cured it successfully using alternative methods. And yes, most doctors are in denial about the existence of systemic candida issues. Indeed, Dr Orion Truss, a doctor himself, even wrote a famous book on candida called "The Missing Diagnosis".
If you want to cure your candida problem, you will have to do it yourself and that's why I would advise that you learn all that you can about this disease because it is so hard to cure. But it is curable, I'm living proof. That's why I also advise that you read everything on my blog about candida. Shown here. I also include a way to completely heal your candida in this blog.
