Hi, Diha.
I think there's no magic pill that will fix damage made by alcohol. Swinging mood is part of recovery, just accept it. We've all been there. Don't drink and give your body and mind a chance to heal itself. While in early sobriety try to avoid situations where is booze around and someone pushes you to drink. Your sobriety is like a baby now and needs protection and support. But later it will grow and will protect you.
Best luck to you, keep posting/
