It's a really great feeling when that lightbulb switches on in your head. I experienced something similar before I joined this site. Just knowing that we can't go on like that forever, and we're missing out on life by being intoxicated all the time is no fun at all. I'm really proud of you for realising this.
The gambling I'm not sure I can help you with. I guess it's another way to escape reality when times get tough. It's way too risky for my liking, I hate the idea of machines eating my hard earned money, or placing a bet and losing all my money even though I was sure that I was going to win. You might win once or twice but overall it's a huge money drain.
Anyway I'm rambling, just want to say you're doing a great job, and with determination, a loving family and support here any time you need it, you can overcome these addictions.
