No way to restore sanity other than solving puzzles?

[Mikezila]

I've ended up at "..." twice so far, and both times I lit the lantern and walked for a bit, and next time I opened my inventory for something it was back at "Heart and head pounding, hands shaking." I'm guessing that if you fall to the danger zone you have to deal with it for a small while as a punishment, but you eventually recover to a somewhat functional state.

I also had no idea that losing your mind gave the enemies rollerskates and night vision. I'll keep that in mind.
