I removed Facebook from my phone because I didn't like how impulsively I was using it at any moment of waiting or downtime.
It was hard-ish at first, and it took a lot of "Do I or Don't I?" before I actually did it. I didn't delete my account or anything, so I could still check it from home, but as time went on and I was _only_ able to check it from home, I would frequently find myself thinking, "wow, there's really not much good here." which is one of those things that only occurs to you after taking time away from it.
I realized I replaced my Facebook habit with an Instagram habit, so I deleted that too. The only remaining distraction is Reddit, but I've never been as impulsively hooked into Reddit as I was the other two.
When people say that it's better without Facebook, they're not kidding. You should try it.
