Yes, that sometimes happens to me, too. I’ve particularly noticed it during intense concentration; e.g., when undergoing detailed cognitive testing (as part of research studies). Things like “repeat these eight digits backwards.”

One thing to be sure your urologist knows, if they don’t have a lot of Parkinson’s experience:

For patients with a neurologic component to their bladder issues (e.g., Parkinson’s patients), it’s recommended to start with a lower-than-usual dose of Botox. The risk of urinary retention (i.e., too much bladder muscle paralysis) is much greater in these patients.

Re mannitol — I’d be surprised if it caused constipation. Mannitol is a poorly absorbed sugar, which means that much of what you swallow remains in the intestine. It then pulls water into the intestine, resulting in softer stool. I.e., it’s an “osmotic laxative”, if you take enough of it. For me, I find that a tablespoon has that effect.
