Haha I can totally relate to this, having worked from home since the beginning of my career 14 years ago.
The most difficult problem for me was separating work and family, something I am still struggling with, especially when my workstation is like 5 meters from my bedroom.
I've thought of renting a small office, but decided it will just add to the overhead unnecessarily.
In fact I wrote a blogspot about my daily life as a freelancer

Thank you for your comment, looks like we have the same problems, I am a video producer and editor and sometimes I really need to be loud. And of course my family is not very happy about that:)
