I just wanted to welcome you to SR!!
Good for you for seeking out help with this.
My thought is that five months seems like a long time for alcohol to be present systemically. Even the pungent herbals I use for my horses that are released through the skin only have a max life span of 30 days. Could a slow metabolism be the culprit?? My boyfriend has not quit drinking longer than a week, so I don't have first hand experience to share, unfortunately.
More time will tell.
Peace to you during this time. Keep posting!!
