In this article from Dr. Mercola he recommends exercise, and more specifically, swimming as the best exercise for insomnia. He has this to say about the bike:
"For most of us, cycling is not a good practical alternative for two reasons. One has to cycle up to four times longer than most other aerobic activities to obtain similar cardiovascular benefits. However, the more important issue is that most of us ride on the roads and expose ourselves to being seriously injured or killed by cars or trucks."
It's a fascnating place to be; my body is telling me that I'm exhausted, and yet I can't close my eyes. Prednisone, I'm learning, makes me squirelly as hell. No mood swings yet though - I feel pretty darn tootin' and cheery right about now!
I have to start triathlon training again. I want to compete in least one off road tri this year. Any suggestions? It'll have to be late season.
