Over do it much?

Worked out this morning for the first time in awhile.  (Medication for my migranes had zapped every ounce of energy I had--better now).

I digress.  Let me start again.  Worked out this morning for the first time in awhile.  Cannot lift my arms above my head and even keeping upright to type this post is a chore.  I was fine until about 4:00 or 4:30 this afternoon, then, like a ton of bricks, tired, exhausted and oh so sore.  But a good sore.
