Another suggestion, If you're working on a side project or studying, try to do it early in the morning ( for me it's 4am ), you'll feel less distracted.
Early morning works well. Most of my effective pomodoros are before 11 am. I start around 6 or 7 am, and get most of the crucial things I want done for the day, done.
I don't even try to work after dinnertime if the work requires a lot of discipline. They never pan out for me. Better to sleep earlier and spend morning hours more effectively.
