My dad was diagnosed with Parkinson's in January 2012 (though he was showing symptoms long before then). He is currently on Madopar and Comtan. We also tried Mucuna Pruriens as well.

Two of the most difficult issues he faces is dizziness and fatigue. It seems to get worse after he takes his meds, which makes taking them during the day pretty problematic. He's tired without the meds, but after he takes them he's even more tired. We noticed that it is generally better at night.

I've researched some solutions for this, but they mostly point to more medication (ie. antidepressants, etc), which my dad is unwilling to take.

These issues are preventing him from getting enough exercise during the day. Any tips for managing the fatigue and dizziness, or getting more benefits from exercise would be much appreciated, thanks!
