my technique has always been "if you need to do something but your ADHD won't let you, refuse to do anything else in the meantime". it takes less effort than suddenly deciding to get up and do the thing, but if done properly, culminates in you eventually deciding to get up and do the thing anyway. never thought of the holding breath thing though, that would probably result in less literally-fifteen-minute pauses wouldn't it
