The most successful advice I’ve found is to find a way to reset after meetings without using your computer. For whatever reason, they’re emotionally drained after meetings. They get back to their computer and reach for Reddit or Twitter or something for a low effort snack, which then spirals into an hour or more of doomscrolling or distractions. This then translates into self disappointment at their low productivity, which further drives them to seek more cheap online entertainment and the cycle repeats.
So try something else. After your standup, go for a walk. Don’t use your phone. Do some stretches if you WFH or have a quiet place. Whatever you do, don’t fall into the rut that destroys your productivity.
