Sometimes when I’m uncertain if I really want to chug a couple liters of cream and sugar mix before bed, a funnel makes the impulsive action happen really fast. It’s easy to make up a funnel by just cutting a hole in the bottom side of a two liter plastic bottle. When ready, hold the bottle to your mouth, hole side up, and fill the bottle with whatever you want to hammer down. Hold your tongue against the top until the thing is full. Then just release your tongue and tilt the bottle vertical, minding to not let the little bit undrank yet spill out the hole you cut!
