Metronidazole (flagyl) helped me with regular bowel movements more than anything else

I’m not sure what pfs is but I’ve been insanely constipated since it started and that seems pretty universal.
I read a thread or two on here and another on the pssd subreddit and decided to try flagyl. I took 500mg 3 times a day for 7 days. By day 2 I’d say my bowel movements became much more regular, like they were before. I started getting the urge to go after eating, just like I did pre fin. I’d also have a bowel movement in the morning. Not to be too explicit but the movements themselves weren’t perfect, but much improved.

I also felt a few very weak mild spikes of libido return. Additionally, my joints stopped cracking almost entirely and my skin symptoms also largely got better. I’m not sure what causes pfs, but I think, at least as a downstream effect, alleviating gut issues is pretty huge in improving quality of life. The downside here was that my sleep issues continued to be very rough.

I might revisit this and add some more antibiotics in (someone said they got cured from pssd by getting treated for h pylori- although they were actually diagnosed). I’m not saying we all have that (that seems wildly unlikely) but perhaps many of us have slowed bowels which resulted in dysbiosis.
