Resting up vs. pushing too hard

[RoadRaven]

Then after the ride, I literally crashed. Couldn't muster enough energy to fix myself something decent to eat (so I just had a bowl of cereal and a big glass of milk), and then went straight to bed. I'll tell you what...when I woke up this morning, I could've eaten a horse!!!

This is a really normal and expected reaction and it is most excellent that you listened to what your body was saying.

After a good workout, you should eat a little, rest/sleep and then eat again.
Any good training book will tell you that this is a good way for your body to respond, and you should listen to what it tells you.
