Has anyone here had H Pylori and did the treatment work first time?

Hi Fluthers!
Well I have h pylori, diagnosed by a stool test. Great, I feel scared and worried about stomach cancer and wondering how long I’ve had it for as I’ve had gastric issues for about 10 years! Anyway I’ve been reading about the treatment and it sounds quite intense, and I’ve been reading that sometimes the treatment doesn’t work the first time – anyone here had this bacteria – were you able to eradicate it first go and was the treatment hard? Thank you x
