My ex-abf was a binger. He started out using every 90 days or so, even went 5 months one time. Then every 6 weeks, then every 3 weeks, then every two weeks, then every week...then he got arrested and went to prison...guess he is not using now, but, who knows.
Keep in mind this is a progressive disease, the amount they use and the time frame between usuage will become more often...they will also stay out longer, goes from a night, then two, then three and so on.
