How did you overcome the need to know?

I have been NC for 4 months as of yesterday. This is the longest I've ever made it after a breakup in my 3 year, long-distance relationship. My ex doesn't have any social media presence, other than LinkedIn and he already disconnected from me there and his profile isn't searchable. I struggle with wanting to know what's going on in his life. I found myself doing google searches, hoping to find something. I know it's likely the addiction driving it, but it's so hard to go from knowing everything about him to nothing overnight. I just can't seem to shake the want to know. Can anyone relate and if you can, did anything, other than time, help?
