Breaking the muscle memory has been the hardest part for me. I don't have that much investment in Reddit succeeding and I'll be damned if I don't try to tap the app on my phone 3 or 4 times a day still, even after deleting.
I deleted my account and my 3rd party app and I found myself reflexively tapping the now-empty spot on my home screen 5-10 times yesterday. Today I haven't and only went to the mobile site a couple times to see what's going on with the state of things, but left as soon as the first "Oops, this /r/AskReddit text-only post is NSFW, open in the app!" message came up.
I have however visited HN and kbin 5-10x more today.
