I switched to a flip phone. The benefits strongly outweigh the advantages of being hooked on a smartphone. My sleep has improved, the quality-time I spend with my kids is actually quality-time now, and my night vision has even improved (this one shocked me the most).

It's not for everyone, but I have a very addictive personality when it comes to technology.

Edit: I see you can't do that because of professional obligations. What about carrying around an iPad - it could be more of a barrier to just random surfing?
