No problem - I'm glad to help, if only keeping you company during your frog troubles.

I've been there and I understand. Might as well use my insomnia to good use :P He's settled down, at least, which should be a good sign!

From all indications, he sounds "frisky" and that's all. You aren't seeing any other indicators (skin changes, lack of appetite, etc.). And he certainly isn't lethargic :P

I do think it's entirely compassionate of you to stay up with him, though! You've earned your "karmic medal" for the night!
