I'm really happy for you. I saw an internist too and I too came back positive for H.Pylori. He gave me Antibiotics to treat me as well. I did the regimen and my odor did subside, but it was short-lived and the odor returned not long after. I really wish you better luck though because we do not all suffer such misfortune. Stay strong and keep taking plenty of probiotics because as you stated, Antibiotics can kill all the good bacteria, causing trouble for your body. A common problem that arises is a yeast infection, so if anything starts itching down below, seek treatment ASAP.
God is good and even though he's given me a heavy cross to bear, I have a strong, positive feeling that he will lead me to the light at the end of the tunnel. I have too much potential to be stricken with this illness forever. It's already been too long, but I know that there are brighter days ahead. Stay strong and I wish you the best :)
