Resolving SIBO - herbal supplements or antibiotics?

Hi everyone - I have methane SIBO. I suffer from chronic migraines, fatigue and constipation. Based on my research I can either resolve with a stepped process of herbal supplements, or antibiotics.

The herbal supplements approach takes 4-6 weeks and the antibiotics takes 14 days.

I’ve done a lot of research, used AI and have read several posts on this sub.

Whilst it seems like a no brainer to do the antibiotics route due to time and cost, some people seem to suffer from bad headaches on this approach.

I’m keen to get views on which works best for people. Thanks!
