Nervous about specific HPylori protocol😬

Hey hey! So I was diagnosed with HPylori a few months back and I’m nervous to start the protocol. I also want to know which protocol were prescribed with the best results. And please let me know I I should request a different combo. I received Tetracycline 500 MG, Metronidazole 500mg, Omeprazole Dr40 Mg, and Bismuth 262 MG
