Scared to take Metronidazole

So I’m pretty prone to getting BV, and I just got prescribed the pill form for the first time in years. I don’t remember having any side effects the first time I took the pill form, nor did I have any when I used the gel version.

I’ve been having some stomach issues for the past year and already experiencing debilitating nausea because of it. All these Metronidazole horror stories have me a little scared to take it. Does anyone have any success stories?

Should I be worried if I haven’t experienced any side effects before?
