Trappist drinking?  This was best expressed many centuries ago by Li Po (701 - 762 CE), who wrote a reflective verse on unaided, single-handed swigging, called Drinking Alone by Moonlight:

    A cup of wine, under the flowering trees;
 I drink alone, for no friend is near.
    Raising my cup I beckon the bright moon,
 For he, with my shadow, will make three men.
