Hi Peter
You said you were looking into Mucuna Prurience. I tried that and I don't recommend it. I ordered some from a company in India, and it arrived in the form of a pink powder in plastic containers which a scoop in each. There were no instructions regarding dosage nor a list of contents. It could have been anything. Anyway, I started taking one scoop twice a day in a glass of water. After a week it had made no difference to my leg drag or arm tremor, but it did make me throw up violently. Now I know what they mean by projectile vomiting! Another technical point which I missed is that although this preparation may contain dopamine, it cannot cross the blood-brain barrier, so it merely floats around the body and makes you sick. Only a dopamine precursor can get the dopamine to where it belongs. I stopped taking it because my wife (wisely) flushed the whole consignment down the toilet in case I was tempted to try it again.
Beware in general of herbal remedies. They're not regulated, so we don't know whether they contain what they're supposed to contain, and they may also contain undesirable ingredients.
I was also desparate for relief from my symptoms and at the same time didn't want to start on drugs for fear of the side effects. I delayed starting for about seven years after the symptoms started, and now I take Sinemet 25/100 twice a day and sometimes only once a day (more makes no difference), which I figure should be less harmful in the long run than a higher dosage. Time will tell. Now at least I can walk without leg drag and I don't spill food from my fork (my tremor is on the left side), which is very embarrassing in company.
I exercise daily and find that strength training (weights) does the most good, but I like cycling most of all because on the bike I feel absolutely normal: normal balance, no tremor. It's weird, but there's apparently some neurological reason for this. Go to Google and enter cycling + Parkinson's Disease and you'll find some interesting stuff on the topic.
It's nice hearing from you. I agree that you should delay the meds as long as possible. Courage: you may be one of the lucky ones with a very slow progression and symptoms that don't interfere much with your daily activities. .
