Garglin I bought with my own money

This is Garglin that I bought with my own money.

I don't think there is anyone who doesn't know.

I bought it at a pharmacy, and sometimes I gargle before going to bed at night.

I use it as a mouthwash instead of brushing my teeth after drinking beverages.

They say it is actually bad to use it right after brushing your teeth.

They say it's best to use it about 30 minutes after brushing your teeth.
