Welcome CD - It's great to see people such as yourself looking seriously at their alcohol intake before something bad happens. I was a closet drinker, too, and kept putting off quitting, but didn't like the way I lived at all.
I found out that I had nothing to fear by getting sober and everything to gain. It takes some time, but it's wonderful to feel free from the compulsion to drink.
Keep reading and posting - there's a lot of people here who really understand and can offer support.
