How I kicked the same problem:

Spend a day procrastinating. Contemplate how unpleasantly wasteful it was (even if it felt superficially 'fun' at the time.)

Spend time being productive. Contemplate how I enjoyed doing it, and how I enjoyed having done it.

Consider the contrast between a day spent (in my case) learning C++ versus a day messing around on Reddit.

I don't have to make an effort any more. After my allotted procrastination time is up, I lose interest, and start to feel drawn towards my studies. It's like an internal productivity timer that automatically dampens my enthusiasm for wasteful activities and makes me keen to return to my books. I guess this is what it feels like to be hypnotized into disliking chocolate and into preferring healthier snacks.

Just a friendly caution: overcoming procrastination to study is very different than overcoming procrastination to work. I'm not exactly sure why. Perhaps because learning is more passive than producing. Perhaps because learning usually feels productive, like you're permanently gaining something, whereas a lot of work will lead you to question the purpose of the work itself, and usually doesn't compound in value of time.
