If I try to plan what I do in breaks (use the 5 min to stand up and stretch each time, or stretch the first time and grab water the next), then it doesn't feel like a break and it feels like scheduled work. So , j just do whatever I feel like in that particular moment so if I dont want to particularly get up and rest my eyes, I dont have to exert willpower on that
i like the pomodoro method but i'm not that keen on follow the timer exactly. So, on my breaks, it varies. Some time i go grab some coffee, fill my water bottle, go to the bathroom. Maybe, at work, talk to someone. This may take more the 5 min, but i dont mind. Also, and most commonly, answer messeges on the phone or read one of the tabs i opened during the pomodoro but it wasnt directly related to the work.
i really need to get glasses, i read that as pornodoro! when i used it i did what everyone like me does, smoke a cig, back when i quit for a few years i used to mostly skip work breaks altogether, didnt really see the point if youre not smoking
