I've noticed that after a day of freeriding/DH riding I have trouble falling asleep when night rolls around. This usually only happens with longer rides. I especially noticed this last weekend (rode Whistler on saturday and Vedder on sunday ). I feel tired and beat, but I can't fall asleep at night! I guess I must be a little bit jacked up on adrenaline when I try to fall asleep. Anyone else have this problem?
