Actually you give me some hope so I'll stick with it. I did have those headaches and dizziness but that lasted only a week. I've also been monitoring my heart rate and strangely it's gone up. My normal resting was around 60 - 65 and now is 68 - 78, sometimes 80. That I don't understand but doctor says it may have something to do with diet (and i 've to cut out too much salt).

Anyway, I'll keep riding and pushing and see if I feel better. 3 weeks ago I was feeling great and now, I feel like I'm starting all over.
