Hi Sacha, I am just over 5 months sober and learning every day. One of the many clues I had that there was a problem was when I was filling out a profile sheet for something and it asked me what my hobbies were, I drew a blank. I didn't know. And that was because I didn't have any. I drank. And watched tv or played on the Internet.
I think that you will find here that you aren't alone, there are going to be tons of people who share a similar story to yours and even those who don't, will be able to sympathize.
I am accessing this from my iPhone so I can't get you a link. You could look at the different threads that Dee has started, surely it will be there.
