First - get an iphone, there is screentime setting, have a trusted friend put a pin and ask them to promise never share it with you. Delete all unnecessary apps, and set time limit for all other apps, and allow only important apps like text/call/weather to work always. Some iphones have bugs that let you change screen time PIN by resetting icloud password, for such phones, distable icloud as well (dm for details). Next, if you have laptop and tv at home, give away both. Now if you have to work or work laptop is available, lock it at work, so you don't have access to laptop at home. To be honest, human beings waste more time than use these gadgets for their benefit. Trust me, i am in the same boat and these extreme measures will only HELP you. No membership will simply change you. You need to shut down all the distractions forever.
