Having been there I found there are two side, removing distractions and mentally retraining yourself. The latter takes time. To remove distractions I have turned off all notifications (you don’t need them), declutterd my desktop (delete unnesesry apps, remove distracting ones you still need from the dock on macOS). The biggest for me though was blocking sites like Reddit, just point them to the loop back ip in your host file, no need for clever blocking software, just pertinently block them.
