Antibiotics wrecked my gut 2 years ago — healed from most symptons now, and finally tested IMO positive

About september/2024, did 3 antibiotics rounds over 2 months, to fight a sinus infection. The antibiotics were azithromycin, amoxicillin and moxifloxacin hydrochloride, in that specific order. After the last round, I got some weird symptons (feeling dissociated, light-headed and constipated). The truth is that those antibiotics rounds led me to a dysbiosis state. At the beggining, I was very constipated, having slow motility, several congnitive issues (depressive feeling, tired all the time) and other weird symptons (feeling extremely cold, having some insomnia) - that was april/2025, my lowest point. Then I tried some treatments that eventually helped: (1) motility support (ginger and artichoke extracts, local brazilian brands) + vitamin B1 (benfothiamine), started taking those and got cognitively better within 4 days, and also my gut started making sounds again; (2) gut barrier support (glutamine & bone broth), that completely softened the "feeling tired after" eating sympton over 1~2 weeks, a consequence of huge LPS absorption. Lately, my goal has been supporting my butyrate production, by consuming some specific strains probiotics (bif. longum BB536) and tributyrin (NewBiome brand, 300mg 1 dose), I feel like I feel better eventually but I have to build up on those. Also, I do 5-HTP at night for gut motility, also with some ginger tea eventually. I no longer have cognitive issues, my current symptons are bloating feeling after meals and slow motility. I tend to get worse 2 or 3 days after consuming beer/alcohol, then I have to build everything up again (BB536 probiotic and some doses of tributyrin every other day). The flare 2~3 days after alcohol are like bloating, abdominal distension, gas, feeling tired the whole day, and the curious thing is that it doesn't happen the exact day after drinking, it usually takes 2~3 days so I can really see the gut effects. 2 months ago I was tested positive for IMO (about 15 ~ 20 methane ppm in the first 30 min of testing). All other medical tests completely normal. Feeling much better now compared to 1~2 years ago, but still struggling with some symptons. Waiting for a new appointment with my doctor this week to plan next steps after this IMO test result. This doctor was also the one that prescribed me LDN (didn't help) and AdiDao (DAO enzimes supplementation, helped a lot, I take one before each lunch).
