Removing the device removes the temptation.
Typically I can be in the middle of something else, sit down in front of the laptop to quickly check the news or something, and end up walking away from it a few hours later. It's very easy to get sucked in. I guess I'm weak minded.
I recently bought a new phone that feels physically different than my old one (Nexus 5x vs first-gen Moto X) and I haven't yet used Facebook on it. I think I'm going to keep it that way; I so far haven't found myself automatically going to do it the way I would on the old phone.
