Block it completely, if u watch it on ur phone, block access to it on ur phone, if u have a laptop, throw it away. Get educate on the topic and also, u have to attack those urges when they hit u, by planning ahead of times what to do when they come, don't just say in ur mind *ok this is last time* write something u can read, like for example "this addiction is short term pleasure(5seconds of pleasure, i doubt we can call it pleasure) and very very very long term pain". Either way, u have to go through the reboot, u can do it now whilst its just an addiction and it didn't destroy ur life yet, and the withdrawal symptoms would be less intense or be an idiot and fall onto the same trap again again, until u start developing ED, PE, no libido, depression, no motiviation, fatigue, brainfog... the list is indeed long and there are probly things we don't know about yet.
Here's a trick:
1. Download applock master from playstore( doesnt matter which applock u use, SO LONG AS IT HAS AN **DISABLE UNINSTALL** option)
2. Get into the app put a dummy password for now, it will prompt u for ur email incase u lose ur password, SKIP THAT, u must not have access to ur password at all cost
3. Go into the apps settings and disable *unlock app with fingerprint* and enable *prevent uninstalling*
*important* : problem is that even tho u put the disable installation option u can still uninstall it using ur phone's settings app. This is why we will lock that app using the AppLock master
*important 2* when u restart ur phone, the Applock will take some time before actually blocking access to the apps unless u put in the password and this take us to our 5th step
5. Change ur phone's password(keep ur fingerprint tho), but ur not the one whose going to change it, tell someone whom u trust to change it(someone u trust), this way if u rly wanna watch, u cant restart ur phone and quickly get into ur settings app and uninstall that app. Locking all doors of access.
6. Go back into the applock master and lock the settings App.
7. Put a LONG password of 1's and 0's that u ill forget, this way u cant access the settings app nor the applock anymore.
8. Enjoy, now when u have an urge, u can simply uninstall/disable ur browser app/whtvr has the stuff u wanna watch(as well as playstore cuz obv u can reinstall it afterwards if u dont), wait until the urge goes away, go ask the person who has the password to quickly reboot ur phone and put in the password, so that u can go into the settings app and uninstall the appLock and reinstall the browser or whtvr apps u uninstalled. After that u simply redo the process of downloading the app ect ect.
*important 3* playstore has an option where u can actually deactivate/uninstall apps from it, so disable it when u get an urge as well
Warning ur brain might trick u, so when u get an urge u gotta rush to blocking the apps, before things get worse and ur desires completely take over ur brain.
It would also help if u actually stopped using socialmedia, i uninstalled Instagram. tbh i dont regret, i gained much more time, so yeh, make some progress in ur life ig.
Good luck.
