That's good! Don't rule out SIBO just yet though if you have really bad constipation and still no answers. Not everyone who has SIBO gets all of these symptoms - I don't generally have diarrhea (that's more specific to the hydrogen kind of SIBO) or brain fog, and I don't have joint pain super often either - although my ankles complained the last time I put on platform shoes to try and be as tall as my brother LOL! Ooh I hope your post-covid syndrome gets better; one of my family members had covid and it affected her taste and smell, too.
