Garglin!

I can't use mouthwash that is too strong, so
The product I always use is
This is the mild, alcohol-free Gargrin Zero!

I use mouthwash before bed.
If you gargle all the way down to your throat before going to sleep, you'll feel much more comfortable the next day!
It is heavy to use because of its large capacity, but
It feels reassuring, so I keep ending up buying the big ones :)
