I was extremely nervous when I first posted here, but this forum is the only tool I've used since deciding to give up alcohol in July and I'm now coming up to 6 months sober this week.
You'll find an abundance of support here, but you may need additional plans in place such as AA ect as this kind of addiction can't always be fought alone.
In regards to your husband, it sounds like he has a problem too, but only he will be able to decide whether he wants to address it or not. My husband is a drinker, but not a heavy one and even less so since I gave up, so maybe yours will reduce his intake if you quit. That does however depend on whether he actually has a problem or not.
