Never been fan of mouthwash, unless it was in someone else's mouth - in which case, I encourage it. For one, mouthwash burns. But more importantly, I always found it too inconvenient: the uncapping, the pouring, the drinking, the re-capping, the swishing, and finally the spitting. Not to mention that there's always a bit of liquid left in the cap when you screw it back onto the bottle. But finally, I found a way around all those unnecessary steps.

I put my Citrus Listerine into a squeeze bottle with a little pull-off cap. No longer going for exact measurements, I just pull off the cap and squeeze as much as I want into my mouth and swish away. My mouthwashing time overhead is reduced to 2 - 3 seconds. Damn I'm good.
