• One cannot can fight an addiction by deciding to do boring or not as exciting stuff. You need to find more exciting/interesting activities outside of the Web, be it on reddit or whatever.
  So, the question boils down to: do you have any passion, hobby, side activity you wish to invest more time in it? Now would be a good time. And if you don't have any, now will the best time to start trying out new activities ;)
  Don't be afraid to try stuff and then to change if you do't enjoy them.
• What may also help you is to realize you have one live to live, with a (very) limited amount of time before it's over. We all have.
  So, do you really want to waste any second of your time reading some bullshit and interacting with assholes or morons (that are proud of their crass ignorance and their constant hatred)?
  I certainly don't, my time is way too precious to waste it with them.

Enjoy spending your time doing positive activities. Things that will help you grow and appreciate life even more. Play music, write, sketch, paint, dance, do a movie, sculpt, or go out for a walk, have a look at whatever nature remains near you... while there is still something to look at. Spend as much time as you can with the people you care about, your spouse and your family maybe? Not with a bunch of hateful and dumber than shit morons.

Do you have a pet? If you're able to keep a pet, they're great distractions from the self-inflicted psychological damage from consuming corporate social media

Just remember you don't want it.

Have a trigger to make sure evertrimrbyou have an urge to go on there you do not. Pinch your arm or smth. Put it in a folder on the last page of your phone and the few extra taps and swipes will be enough to remind you or trigger your memory not to do it.

Find out why you go there?

For me, the best way to quit bad habits is to find alternative hobbies. Try something new. Join a local group.
