Burst of energy followed by a crash

Had a real burst of energy this week after making the decision to quit teaching. Felt like a new man and was able to do things I couldnt normally do. 
Now after having two occasions of socialising in two days I feel utterely burned out and crashing, like I cant do anything but sit in my pyjamas.
Does anyone else identify with this:?

  • I follow a pattern of extreme tiredness following too much activity, Then rest.  Then I'm ok a couple of hours later.

    On Saturday I did too much walking, I collapsed into bed at 5pm, totally exhausted, by 7pm I was feeling ok.
