I moved back after college AND after I divorced until I got back on my feet. I had married and was living near Boston, I moved back to Texas and lived with them for awhile.
FOR ME, it didn't work well. My parents tried to give me a curfew even though I was in my mid 20s. I was never the kind to go out and do anything crazy. One night I went over to a friends house who had two children, one of whom was SICK and they told me to come home at a certain time. They also read my mail and monitered just about every area of my life.
For your sake, I think you should get a post office box so you can have some privacy. Since most people have cell phones, you won't have the problem of your parents listening to your phone calls or tracking who is calling you.
It all depends on the parents of course. I wouldn't assume that your parents are going to be too different then they were when you lived with them before. In my case my parents were always very controlling and manipulative, they have continued to be that way my entire life. No change in my life made them treat me any differently then they did when I was a small child, even having a child of my own.
