What should I do when my cough won't stop?

Recently, I haven't been able to stop coughing.
I am going through a very difficult time.
Unable to sleep properly even at night,
It's very difficult to go about daily life during the day.

I went to the hospital, but even with the medication you prescribed,
I'm more worried because I haven't seen any significant effects.

Effective methods when coughing does not stop
Is there anyone who knows?

I tried some methods I found on the internet, but
It hasn't been very helpful yet.

While researching what to do when a cough won't stop

I visited the hospital, and there doesn't seem to be any major issue; they said it's just due to dryness.

When your cough won't stop or when you're dry, try looking for and doing things that might help.

It's not working well ㅠ

Are there any other methods to stop coughing besides this?
Could certain foods or lifestyle habits be helpful?
If you know of any specific treatments for when a cough does not stop,
I would really appreciate it if you could share it.

Please help me when my cough won't stop ㅠ
