Do u think u may have over done things while feeling so good? Its hard to take it easy when your feeling good. It would be nice to have a gauge that could tell us when to ease back. I have cut out the exercise the last 2 weeks and taking it easy, I get a feeling of lethargy that tells me to stop but it would be nice to know before this hits. Im on holidays at the moment and was hoping to exercise some before going back to work, but need to go back and rethink an exercise routine. But when your feeling good its hard not to increase work load Take care, cheers!!!
