I have a similar situation to yourself. Honestly I have found that working environments become "soiled" for me over time. I try to constantly mix up where I am working in my place or get out of the house to a coffee shop to work if I am not focusing. Keeping s good rotation of these work spaces has been a huge boon. Often times I work from the couch in the living room, take a break, move to the kitchen, then end the work day in bed without the TV on. Eventually I will probably move back to working in my office but since the new WoW expansion has come out my office is no good for productivity.
