So first of all, there are (or should be) a lot less interruptions when working from home. People tend to disturb folks that they see, it's a lot easier to give address someone at the other end of the room or across the corridor than it is to call, email or chat with someone. With these disturbances gone, you are more likely to be more productive from the start when working from home and so a little slacking off here and there probably does not make you less productive than what you were at work. That said, self motivation and lack of external pressure can be a problem. When I feel I have a hard time to focus on something my last resort is the pomodoro timer. I sit down, set a timer at 25 minutes and force myself to no break focus during that time. Once the first period is over it's usually no problem to keep going since I've gotten into something by then.
