Wise words, my friend. Wise words, indeed.
Yes, RseCty, you came here with questions asked by others before you. Some of the responses you received were, in fact, biased by those who came before you. Some of the responses you received were probably motivated by years of experience dealing with alcohol related incidents. The fairness of those responses to you is debatable. However, given the, shall we say, evolving nature of the stories in your posts it can be argued that they were warranted.
You need to understand, too, that in this business we see a lot of alcohol related incidents. None of them are good. Many of them have very negative outcomes. I'd argue all of them were preventable. I'll let the others speak for their own experiences.
You're new to us. We don't know you. We have no basis to believe anything about you changing. This will be true in a professional standing, too. The greater the distance between the present day and the incidents in question the better. For now, though, you're still young and too close in time to the events in question. Just so you understand, too, getting defensive, while understandable, doesn't always paint the picture of someone who's learned from their past.
You think you're up to the challenge? Good. Prove it. Understand that you put yourself slightly behind the eight ball both in terms of professional standing and hirability. You are going to have to work harder, longer and do more simply because of your past actions. Understand, too, that we hear all the time "...but I've *changed*..." only to see those people blow it. Simply saying that you aren't the same person anymore isn't going to cut it. Prove it. Keep proving it. The longer you prove it the better your standing. Such is the price for some mistakes people make.
I'd like to add, too, that I also have a significant bias against alcohol. I do not consume it. I've seen people die from it personally and professionally. I've lost family members to it. I've seen lives destroyed by it. I am not unwilling to help people who are trying to improve themselves. Just understand that you're going to have to work harder.
If you're up to the task, despite your lukewarm reception here, this is an excellent place to gain perspective, education and support... even from those who replied to your initial posts in a manner you found offensive (as mentioned, intent is hard to interpret in an online forum). If you're really interested in improving yourself this is one of the best places to do it.
