What's the next step after beating email addiction?

I used to be REALLY addicted to email. When I use to wake up in the morning, first thing I would do is check my email on the phone. After sitting at my desk, I would open my email tab and leave it up all day. At night, I would habitually pull out my phone to see if a new email came in. It was like I was a drug addict always needing a fix. I couldn't do it anymore.
