Good job on recognizing it and taking action to improve. My advice is be totally honest, don't hide anything no matter how embarrassing it could be. I have a very close friend who has been dealing with this for a couple years hard (has been lightly since HS, but took a bad turn a couple years ago). His wife and I talk also and she mentioned that when she went to a couple sessions that it was apparent that he hadn't been totally honest with the counselor and that may be why his progress had been muted. It won't solve anything to hide details.
