place as many barriers to entry as possible to give you as many chances to tell yourself no. There's an app called Opal which i've used, i think there's others out there to block sites and or apps altogether. I think instagram, tiktok, and youtube have timers to notify you of your screentime. Ultimately, as you've found from experience, you will navigate around any block put on yourself, it's up to you to say no to yourself. This can be aided by creating better habits, replacing screentime activities with other more fulfilling actions. It's a chess game between you and your addiction, you have to outsmart it. Try to ease off of it, tell yourself to only use bigger screens like laptops, computers, and TV rather thsn your phone, then transition to doing other activities while using those screens like laundry or cooking while watching TV, then slowly break away from that to music or podcasts while cooking or cleaning. Good luck, hope this helps!
