I drink a bit and party with them too. That coughing biz is very simular to what I've had too.
Today or as of the last few days , I feel better. I'm not ready to run out and spent a lot of money on a new mod. sled until I know what I can take though.
I usally ride hard and in the last few years I've busted up a disc in my back. dislocated a shoulder and severly sprained my foot. I quit cornace dropping, but I like the power and use it often. Long tail walks, climbs and sidhilling. If I have to folow the pack it will bother me a lot.
I think what you said about excersize makes a lot of sense. On those days I feel better , it's time to push it.
