Written to the miracle-working icon of the same name, this akathist appeals to the Virgin for help in healing those addicted to alcohol or drugs; it may be prayed either by those suffering from addiction or by another person on their behalf.  Many miraculous healings have occurred through the grace of this holy icon.

Rejoice, O Sovereign Lady, Thou Inexhaustible Cup that quenches our spiritual thirst!

What is an Akathist?  An akathist (Greek, akathistos) is a hymn dedicated to a saint, holy event, or one of the persons of the Holy Trinity. The word akathist itself means "not sitting." (Source:  https://orthodoxwiki.org/Akathist)
