I like to use this when I travel because it comes in under 3oz travel sizes and it's available at my local dollar store for $1. It's a great alternative to my day to day mouthwash, and I don't feel bad leaving it behind if I have too much in my carry-on. I have a bunch of full size ones in the pantry that I haven't tried for more than a few days on trips. I'm definitely open to using it more often, I just haven't had a reason yet. Maybe it'll be next in line!
