Welcome VDGS. I too drank in secret the past few years, and I have people in my life that deny my problem when I've mentioned it. It's frustrating. Some people just don't want to accept it. It's a big resentment of mine.
One thing I've realized, continuing to drink does nothing to change this. I think the problem may be in them and not you. Fact is, you feel you have a problem and want to quit, and you should. Glad your here
