I'm having the exact same problem. There's really not a whole lot to do where I live so before it was just all about getting together with friends and drinking, and now I never hear from my friends at all anymore. It really sucks trying to make a huge change alone, and its so hard to just go out and find new, non-drinking friends. Before I was always meeting new people. Granted, I was drunk so I was much less apprehensive about approaching people. But now that I quit drinking, I'm way too shy to even try.
