I wonder if anyone else has experienced this:

I was taking Benicar and Crestor along with Stalevo and Mirapex for the PD. Long story short, I quit taking the Benicar and Crestor and I feel really great. I have more energy, the Stalevo and Mirapex don't wear off as fast and I just plain feel better.

If things aren't going well with the meds, you might consider going to your pharmicist or Dr and see if there are any conflicts with the meds.
