at the beginning of one of his team's Monday clips in the evidence folder, JD can be heard in fact telling Amber, plainly and with no mockery or sarcasm in his tone:
"I am an alcoholic."
...in other words, I'm pretty sure he knows, and is somewhere on the continuum of managing his problems with addiction, which as I've always heard/been told, is "a process".
Yep, I know that he knows he has an alcohol problem and admits to it, I just meant I hope he realises the effect it has on his personality in a way which his other vices don't appear to if you see why I mean?.
I think perhaps he has never been around people as much whilst drunk as he was when he was with Amber,so possibly has never found himself in a situation where he behaved so out of character.
I do believe he has stated he has been cleaning sober for a good while now (possibly not including weed but I wouldn't count that personality) which is great!.
