Welcome, Lloyd -- to a club you'd rather not belong to!
The beginning of your case of PD is similar to mine. But when I was first diagnosed, Azilect was not yet on the market. As soon as it was available, my doctor started me on it. Like you, I saw no results in regard to symptoms. But don't give it up unless side effects force you to, because its long-term purpose of slowing the progress of the disease is its major value (according to my doctors). There is no way to tell if it is actually working for me or if I'm just phenomenally lucky, but I can tell you that I have now had PD at least 17 years and am still in the first stage.
I do have symptoms that I'm aware of every day, yet they are subtle enough that most people do not even notice them. They are minimized by Mirapex (pramipexole), which worked for me within two weeks. I have heard of cases in which results came even faster. But, as you know, every case is different with this bizarre illness, so predictions are useless. You and your doctor or PD nurse have to find the right combination for you.
If you exercise regularly, keep a positive attitude, and find effective medication, you're doing about everything you can. Best wishes,
