I've know a couple people in my life that went to Mexico to stay for a bit, usually with relatives. At first they love it and then things become a struggle. I guess unless you have money it's a pretty rough environment. The only person I know who came home faster from a prolonged trip was a lady who said she felt like God was sending her on a mission to help people in Africa. She sold everything she had and went there to stay on a church mission. She was back in a couple weeks saying she couldn't understand how anyone could live with so many bugs. Two weeks in Africa drove her buggy.
