I read the issue for Rogue and Gambit. If you read the little in between pane, it has a set of text messages between the two that explains why Gambit was drunk. It wasn't alcoholism....he and Rogue were on vacation, had reservations at a fancy restaurant, she was late, and while Gambit was waiting he ordered a bottle of wine for the table and then she kept getting later and later and he was drinking it.
Not great, but....Not completely gone. Worth noting, anyway.
