I never used pomodoro technique when I was more in control of my time (as a student), and could do 12-14h of focused work: interrupts would have killed off any flow. However, that only really worked for solo work, and collaboration really spends my energy much faster. The first question is why did you start doing pomodoro in the first place? What problem is it solving for you? Is there a different solution that does not cause wasteful interrupts?
