I had similar concerns when on antibiotics for helicobactor pylori.
Would the antibiotics work and could they stop the symptoms and hypos? (not that I knew I was getting them!) Didn't have CGM then.
It does seem as though it's working, and the CGM results are encouraging, the experimenting, the knowledge you have gained about the causes and the symptoms that occur, will help as the antibiotics finish. And then more testing. It's a time of trial and error. You will find a lot about your intolerance to food, your body, your habits, your tastes, what you can and cannot do.
Good luck with it all.
Yeah, you're doing great.
Slightly blue but spring is coming nearer.
Best wishes.
