John,

Your routine pretty matches mine. How are your sleep habits?

I am not sleeping enough hours at night. Nighttime sinemet & comtan helped, and if I wake up middle of the night one 25/100 Sinemet to help release muscles (dystonia) helps.

Davis Phinney has a good video/presentation on sleep habits.

Exercise does help me. Today is first 100F day, with humidity heat index at 110. Not sure how long I'll ride the bike this afternoon.
