Turning 55 in two months. I gave up drinking last year and made it seven months. Then I started heading down the road towards divorce and completely relapsed. I've tried to stop several times over the summer. I made myself really sick from drinking over the Labor Day weekend and it took a week to recover. I haven't had a drink since the last day of August. This time, it's going to happen--for good.
On edit: I also got diagnosed as severely depressed about two years ago. I got put on an SSRI medication which helped a lot. But I still enjoyed the escape that booze offered. I wasn't happy in my marriage, nor was my wife. Now that we have split, I look back and see what an idiot I was. But that's now in the past.
I've got one kid, a 19 year old who is a sophomore in college. She says she will never drink, and I believe her. She saw what it did to me. Fortunately, I wasn't a mean drunk--just a stupid one.
