I was diagnosed exactly 2 years ago and so far, with the help of medication - mirapex ( pramipexole) .75mg 4x/day and amantadine 100mg taken at the same times - I lead a relatively normal life. I have been lucky in that I do not suffer any side effects from either drug (you should be careful with the mirapex or any dopamine agonist as they can cause serious side effects).
I started out like you with a tremor in my right hand/arm and severe cramps in my lower right foot and leg. My handwriting was terrible, I had trouble swallowing and later had problems with excessive saliva. My GP referred me to a neurologist. My first neuro said I should stay off drugs until absolutely necessary; my second neuro's philosophy was (is) to get the best out of life while you are young - so take the drugs. I went with the second neuro. All symptoms have gone now and only reappear when I forget my drugs.
This forum, and the good people in it, has been a valuable resource and inspiration. You will see some of them have had PD for a long time and still lead relatively good lives. Knowing that has helped me think positively.
I remain optimistic about my future and I think that outlook is very important to managing the condition. So, get some good drugs that work for you, exercise at least 4x per week, and keep your chin up and believe there will be significant breakthroughs in the coming years.

. Writing in it is cathartic for me and I try to write at least a couple of times a week, detailing my progress. (Nothing commercial on the site, just one man's diary)
Best wishes and welcome to the community.
