FMT for treating dysbiosis triggered by probiotics: Experiences?

Hello,

I am interested in (anonymous) anecdotes from/about people who have experienced something like the following:
Took probiotics, and then developed intense brain fog and fatigue and some gut symptoms.
Took antibiotics and got better.
Then the problem came back. (This part happened to me.)
Then tried FMT. (This is what the gastroenterologist says that he might offer me.)

Have you experienced this or heard about experiences like this online?

Was it capsule FMT, or delivery to the duodenum, or delivery to the colon?

Did the person get better?

Hearing some real examples would be very useful to me because in the research literature I can only find loosely related examples, but not any data on this exact problem and treatment.

Obviously I will ask the gastroenterologist who suggested FMT about what his experience has been with previous patients, but I don't think he has used this exact treatment before for someone with this exact problem / history. He says that it has been useful for some similar / related problems.

Any experiences that you can contribute would be a great help to me.
