Denial of fukking what lad? Sounds like a load of bs to me....unless there are feelings you are not telling us about. You are in your twenties, tell your lass from someone who is a tad more grey in the hair region that men are just men, we never grow up, we just get slighty less immature, we will always get wrecked at any given opportunity and if you don't have responsibilities, then why the fuck not.
My wife had a similar conversation with me about 4 or 5 years ago (my menory is vague with the exact date), I think that was directly after I had blacked out and fallen into a canal while retrieving my bike, lol. She never said she would leave me, she just begged me to try and control my intake more. Learning your limits is the hardest thing to do. If you can do that she can't complain. If she still complains then there's another issue at hand imo.
Good luck and cancel that fukking doctors appointment. What you going to get, some drugs that send you loopy?
EDIT: and I can honestly say I have not had any further episode since the canal incident. Start counting your drinks!
