Is it actually possible to overdose on cough drops?

When I was little I had a friend and she was suppose to spend the night but then said she couldn't come because she overdosed on cough drops. She only had cough drops because I had seen her earlier in the day and I had them. So, she asked her mom to go get her some and she did. I only had them because I had been sick with a cold or flu and was getting better, but still had a cough. That's why I had cough drops, because I needed them. She only wanted them because I had them lol. Anyway, even when I was little and she said she "overdosed" on cough drops, I thought it was a little weird and impossible. Especially, since all she got was stomach ache like if you were to eat too much. That's it.

Thinking about that now, I still think it's impossible but I'm also not a doctor or any expert of any kind. I know no one here is an expert either, but I'm curious what other people think.

Do you honestly think it's possible to overdose on cough drops?
