4 months of protocol hasn't worked. Worse Biomesight results now than before...

My symptoms since COVID were:
- Bloating
- Loose stools
- Daily skipped heartbeats (PVC's and PAC's)
- Mood issues
- Poor sleep quality

Did a Biomesight stool test and worked with a practioner from The Microbiome Group for 4 months now.
The results were:
- Very few Probiotics left (almost no Bifidio / lacto / akkermansia)
- High Methane producers
- Low Butyrate producers
- High proteobacteria
- High H2S producers

Started 'treatment' with daily:
- Biome Relief
- Biogaia Protectis
- GOS (was added later)
- Allicin Max
- S. Boulardii
- Curcuma extract (was added later)
- Daily green tea (decaf)

About 8 weeks in I started noticing an improvement in stool quality, frequency as well as way fewer bloating. So far so good. We continued with the protocol. Did a new test after 4 months. The results are:
- No improvment in probiotics (even worse actually)
- An Increase in Methane producers
- Decrease in Butyrate producers
- Huge increase in proteobacteria
- Increase in H2S Producers

So basically, the opposite of what we wanted to achieve. I must admit that I did not take much of the Allicin Max, as this gave me heartburn and the specialist told me to not take it then. For the rest, I sticked to the protocol.

I don't understand why my bloating + stool symptoms are better, despite worse results. My daily heart palpitations are ongoing still. I am at my wits end. I have spend a lot of money and time on this, but the results indicate things are much worse. If anyone can shed some light on this, that would be highly appreciated.

Thanks!
