The grace of God IS stirring within you -- because you express a desire to change your deteriorating situation. Cling to Christ, Who WILL see you through this!!
When I urge you to prepare for, and make a thorough sacramental confession, I am not (!!) recommending this as a punitive measure, nor because I think you are a bad person. Rather, I know from experience -- and you do too, since you are Orthodox -- how purging, cleansing, healing and strengthening is the mystery of confession. A prayerful, compassionate confessor is a superb ally when one is struggling!
There are prayers to be prayed by those who suffer from troubling dreams. Do you have them?
If you have close blood relatives who struggle/d with alcoholism, you are at physical risk, yourself, for vulnerability to the disease. Think through your family tree. If you have been tempted by alcohol in the past -- and perhaps even if this is your first time -- don't hesitate to seek outside (secular) help, as well. "Occasional" easily can shift to "frequent".
Establish what in your life is breeding unhappiness for you: job/lack-of-job, marital relationship, friendship/s, finances, physical/mental health, etc. These things heavily influence our spiritual life. . . . and determine what measures you can/should take to improve your external life.
No matter what happens, DO NOT yield to any temptation to stay away from church services and from the mysteries of confession and Holy Communion. You want to place yourself where you are protected from Satan and his determination to destroy you.
May Christ, the Theotokos, and your patron saint protect you!
[P.S. Keep your prayer rope in your pocket, wherever you go -- and pray!]
