Hope it lasts! It's great that you're out of the funk. Mine is still rolling along it seems. No sleep. Still energetic. I don't really play video games anymore but doing plenty of other stuff that keeps me riled up. Don't tell my pdoc!

Oh and yes we know there is an eventual crash. But, because we are aware of that, it should help soften the blow. So then maybe it won't be a "crash" but more of a "slow-down and stop". At least that's what I'm hoping for!
But for now screw it! Keep enjoying it while you can!
