I have had H PYLORI for about 10 years now.

1) Took a bismuth based Quadraple therapy in November 2020
****After taking this i tested positive for HPYLORI 3 months later in Gastric endoscopy

2) Took a Levoflaxicin based therapy about 3-4 weeks ago, in April 2021
Outcome: ****Not fully cured, still have mild gastric pain

My questions are:

1) Are there other sharper, personalised therapies that guarantee success. I do seem to have bacteria that are resistant to antibiotics....... and an extremely sensitive set of intestine, that make H PYLORI difficult to live with.
2) Does cranberry juice and garlic water work to relieve some of the issues and reduce the potency of H PYLORI?
