I've written an in-depth article about this:

Reduce proximity and exposure by design
I discovered that overcoming my smartphone addiction was "relatively easy" while it was way more difficult to deal with internet addiction on my computer.
Especially when I wanted to get work done and engage in deep work habits.
For most people, the computer is still the place where we can work most efficiently.
The big advantage of using a computer to access the internet is that it's LESS convenient and therefore easier to not use the internet too much.
The whole approach is based on reducing proximity and expose to the internet and our smartphones.
This will remove most of the triggers that start the addictive hooked model. It will also make it much more difficult to engage in the 2nd step of the model and perform the action tech companies want us to take.
By designing an environment that removes the trigger or and makes making the action much more difficult, I was able to overcome my internet addiction.
If you follow this you will be able to do the same.
The secret ingredient I used is something I stumbled upon in Kelly McGonigal's book "The Willpower Instinct" and it's called Delay Discounting.
Delay Discounting
Delay discounting is a mind trick recommend by behavioral scientists.
Researchers found out that the longer you have to wait for a reward (e.g. checking your favorite social media site or playing a game online) the less it is worth to you.
The reason is that your brain chooses immediate gratification at the cost of future rewards because immediate rewards trigger the older, more primitive reward system and its dopamine-induced desire in the brain.
To make this work and to delay gratification, the prefrontal cortex has to be forced to cool off the promise of the reward.
The reason is that even small delays can dramatically lower the perceived value of any temptation.
In practice that means your urge to visit Facebook, Reddit, Youtube etc. or playing a game has only a narrow window of opportunity to overwhelm your brain.
As soon as there is any distance between you and the temptation, the rational part of your brain takes over. For example, even putting your phone on airplane mode and putting it in the drawer will work.
For your smartphone:
1. Delete every app that is potentially addictive from your phone.
2.Download the app Appdetox and add times for apps that you have to use less often but cannot delete completely.
3. Download the app Applock for android to block the play store and your internet browser
For your computer:
The Approach That Worked For Me Using the FindFocus (https://findfocus.net)
1.Block distracting websites throughout the day.
2.White-list all the websites that you need to work and force myself to unlock the Internet (for max. 15min per session) if I want to visit a site that’s not needed to be productive.
3. Block email during the day, while still being allowed to send email without seeing the inbox.
Works like magic for me!
I can access almost any website (except proven distractions & email) all the time but for a maximum of 15min at a time.
