Before I got sober I used to feel that way all the time, and I moved around a lot. Usually didn't live in one place more than a year. Now that I'm sober the feeling has lessened somewhat (I'm no longer moving around unless I absolutely have to) thought the wanderlust is still there. For me it's wanting to explore my natural surroundings. I think the natural world is beautiful and I want to see it all while it's still here. I know logically, though, that travelling presents too many implications for me anymore to be truly viable, but it's nice to dream. Needless to say I can spend a lot of time on Youtube and using Google Image when the mood strikes me.
