I would just ask the elders, "I need help, what can be done for me?
They are supposed to minister to you judgment comes if evidence of unrepentant behavior manifests itself repeatedly after the plea for help.
The reason I say this is, each congo is different. I would think some have elders that drink every night and some have teetotallers. When I was 23 or so it became knowledge to the elders that I liked to drink. Just one elder in passing asked, "How're you doin' with that?" I said, "Fine, fine." That was the end of it. I went on to become a full blown functioning alcoholic alcohol abuser. Big difference. I used to drink a ton but I quit and I can be around drinking or have a beer myself and have no problems "relapsing" as it were.
