Sue, I also suffer from fatigue. I fact, it is the most difficult part of PD I have to deal with. I often seem to feel "out of breath" and weak. Before I was diagnosed I slept all the time. I don't sleep as much since starting PD medications: Sinemet, Parlodel, (both very low doses) & eldepryl, and Vitamin E (2000iu.). My neurologist started me on the Parlodel about 10 months ago specifically for the fatigue (energy), and it has helped. I take one-half of a 2.5mg tablet 3 times a day. However, the fatigue has been slowly building recently and I am considering asking my neuro. to increase it slightly. I also take an antidepressant, Effexor (75mg twice a day), which my doctor said might also halp my energy. Another thing I feel really helped was water therapy (exercises) in a swimming pool--you feel great if you do it regularly---which I haven't been able to do this summer. Hope this is of some help.
