I used to, still do to some extent. I've never had any treatment for it. I used to pick at my face all the time, it was extremely embarrassing. The only way I could stop is to grow a beard so I can't get at the skin. I'm sure I have tons of scars, and my beard has patches that don't grow right. Unfortunately that lead to pulling beard hair, but no where near as badly and only if I let it grow past a certain in length. I pick and chew skin in other places still. My fingers are a mess.

For sure it was worse in the evenings for me as well. Also really late at night after my parents had gone to sleep and there was less chance of getting caught in the bathroom for hours on end...
