It was the first thing prescribed to me, but I was only told "it's an antibiotic" and I had no bad issues with other antibiotics so didn't expect that I needed to be careful.

I probably took at least four more pills than I should have, even though I had a bad reaction after the first pill, I assumed it was something else that was causing it at first.

Glad I eventually made the connection, read some horror stories to confirm the likely cause, and called the doctor to switch my antibiotic before I had taken all 30 pills. Might be a lot worse off now if I had.
