I've run dry of coding inspiration / will to code. What are your suggestions?

Why don't you chill out for a while? Pack up and do a 100km hike / run a personal marathon / get that 1,5km swim under 60 mins / improve climbing to 6b+ / if you can't do any better play games I guess. Once it gets boring, go back to coding.

Play video games and chill.
