Here's what worked for me - after trying screen limits, nokia phones

1. Remove all social media apps from iPhone 2. Use Opal in deep focus mode to block apps and websites (I can't exit the deep focus mode - but I allow myself a 2 hour window when deepfocus isn't active) 3. Keep my phone inside my bag - out of sight out of mind 4. Remove "tap to wake up" in settings - you'll have to click the side button to see the screen 5. Deleted slack and email - was hesitant about missing important notifications, but decided to try for a week and realized it made no difference to my work
