I use pomodoro, but honestly only because it's important to get up regularly and walk around or exercise a bit. I work for a bit, and when the timer goes off I do some jumping jacks or push ups. For the longer break (~ every 2 hours) I take a longer exercise period, generally go for a walk around the block or something. I find it helps a lot because I feel healthier, and additional it takes me away from the task for a little bit and can give perspective. Sometimes you get bogged down in a problem, and you become focused on "solving" it...and just taking a breather can help the answer just come to you. Using just the technique by itself without the exercise didn't help much...I often found myself getting distracted during the 5 minute break.
