I did 8 months and it had no noticeable affect, but then I only see my best friends at most twice a year. I enjoy long periods of solitude so it wasn't a big problem for me, but I think most people would probably want to stay in campgrounds and hostels pretty often to get some socialization in. I picked up hitchhikers a few times, which was usually fun, sometimes smelly, and always interesting.
