I don't have PD and can't answer a lot of the questions posed here, but feel bad when new members don't get their questions addressed. I think sometimes this happens because a subject has been discussed ad nauseum, and members assume a search of this forum will turn up more info for a poster than they can personally provide by responding. So here's how to search CP specifically, and not the whole of HealthUnlocked;
Under the Cure Parkinson's logo at the top of the page, you'll find 4 subjects; HOME, POSTS, MEMBERS and ABOUT. Click on "POSTS" and a new page will open. At the top of the page, on the right, you'll find an empty search box into which you can place a key search word. A specific concern might get you more of what you're looking for than will a general one; for instance, "balance issues" rather than "symptoms," benfotiamine" instead of "B1," or "wearing off" or "dyskinesia" vs "levodopa problems."
Hope this helps. I've learned a lot using the search function since someone gave me this tip.
