As noted above, I no longer have any symptoms whatsoever: no fatigue, no illness, insomnia, irregular weight less/gain, nothing. I feel 100% fine, and even after I ride I still feel great, I just don't have any endurance or power and HR is up. You're right, though, that slow recovery and cramping have been an ongoing issue.

The only thing I can recollect that was out of the norm at the time this began was I had been experimenting with consuming increasing amounts of pure salt in my bottles. I have to assume though that a heart condition caused by that would present other symptoms besides poor athletic performance, would it not?
