They call everyone "pleasant" unless you were unpleasant. Medical code :-)
The ent guys do use long term low dose antibiotics, (in our area, we use trimethoprim) for prophylaxis of glue ear in kids. I'm not convinced that the evidence is that robust, and it's likely that your perceived benefit was not related to what you took.
Not the right place to recommend specific treatments on here, but ask what your GP/ENT bod what they think of "Otovents."
If they agree, put up a video, it would add some cheer :-)
