It started slowly after having YE. I got suddenly intolerant to dairy, but I didn't get diarrhoea at that point just nausea after drinking milk.
Then suddenly one morning I woke up with constant nauseous. Whatever I ate I felt sick. At that point skipping eating didn't cause fatigue so I just ate less.
Eventually it lead to awful bloating, couldn't wear pants. Walking would hurt my stomach, I got more intolerant to different food. I would have painful stomach cramps, green and yellow foamy diarrhoea. I had to eat just cooked potatoes, carrots and red meat stew for months to get my system settle down.
I still can't tolerate dairy, wheat, Rye, corn, rice nor banana. Otherwise I have much less symptoms, less nausea. B12, K2, vit D, vit A and l glutamine has helped.
So I assume I was finally able to shake of the bacteria during the years as for example YE goes hiding in the mucus in your gut. So just taking probiotics didn't fix the unbalance. I have eaten a lot of garlic, oregano and basil which are natural antibiotics. And it over here in finland the variety of different berries is amazing and they have healing abilities too. For example bilberry reduce inflammation big time.
